Reel Charlie/armelection.info

We can all admit dating is hard, especially when you're in an environment that doesn't have many suitors.

While finding the right partner for us common folk can take a substantial amount of time, celebrities are known to find love on set with their co-stars.

Although most actors and actresses often date their character's love interest, there are instances where they fall in love with their on-screen sibling. It may seem like a bizarre pairing to the public who are only familiar with their dynamic as family members, but the high number of real-life relationships prove it's not as weird as it seems.

Interested to see who's dated their on-screen sibling? Here are 10 celebrity couples who met on set after winning the roles of brother and sister.

1. Shannen Doherty and Jason Priestley

Two of the biggest stars of 90s classic, Beverly Hills, 90210, Shannen Doherty and Jason Priestley played the iconic roles of siblings Brenda and Brandon Welsh.

While the couple originally denied rumors they were dating, Priestley eventually admitted to Howard Stern he and Doherty were in a brief relationship from 1990 to 1991.  

Despite the fact that their breakup occurred nearly three decades ago, the two still talk about each other in the media.

In Priestley's autobiography, Jason Priestley: A Memoir, he recounted one of the several instances where Doherty acted like a diva when they were about to board a private jet.

"I could not believe my ears at Shannen's very first words after she boarded," Priestly wrote. "Her butt had barely hit her seat before she said loudly to the PR person, "˜Really? A town car? You send a town car to take me to the airport, not a limo?' She sighed a very put-upon sigh. I laughed, as I couldn't really tell if Shannen was kidding or not."

"But that was just the beginning. I looked on, becoming more uneasy by the minute as she began bitching about the short notice and the food on board and the temperature in the cabin and everything else," he added.

However, Doherty refuted Priestly claims, suggesting he is mentally impaired on the Jenny Hutt Sirius XM radio show.

"I love Jason but you know he had a car accident, a racing accident, and I think maybe parts of his memory got altered from that ummm...because everybody changes...they have their own perception of the truth. And his is definitely different than mine," she explained.

"Supposedly I wanted a limo and I've always hated limos my entire life. I find them embarrassing and grotesque. I mean there's things that would in no way happen. Like I didn't even go on that jet at that point in time ...it's like wait wait wait you totally confused me with somebody else maybe from the show? I don't really know. I just know that at some point everybody just needs to sell a book... Right?" Doherty added.

2. Maureen McCormick and Barry Williams

Back in the early 70s, The Brady Bunch was one of television's hottest shows. McCormick and Williams both played the oldest children in the Brady's blended family.

McCormick revealed in her memoir, Here's the Story: Surviving Marcia Brady and Finding My True Voice, that had a crush on Williams since the series began, but they didn't begin to date until 1972.

"Barry and I went for a walk on the beach and kissed. It was long, passionate and deep. But a part of me"”admittedly a tiny part"”said to myself, 'Oh my God! I'm kissing my brother.'"

Unfortunately, the couple's romance wouldn't stand the test of time, and by the series end, they would go back to just being friends.

3. Chris Pratt and Emily VanCamp

Before Chris Pratt was known for his roles in Parks and Recreation and Guardians of the Galaxy, he starred on Everwood as Bright Abbott, which also featured Emily VanCamp as his on-screen sister, Amy.

Prior to his marriage (and subsequent separation) Anna Faris, Pratt and VanCamp were together from 2004 to 2006 before they quietly broke up near the end of their series' run.  

4. Will Arnett and Amy Poehler

Unlike the rest of the celebrities on this list, Will Arnett and Amy Poehler were already married when they starred as brother and sister on Blades of Glory. They played the roles of a competitive figure skating pair who had a seemingly incestuous relationship, which made fans either laugh out loud or feel incredibly uncomfortable for the entire movie.

But, during an interview with Collider, Poehler said their on-screen kiss wasn't actually them.

"Those were doubles. Those were kiss doubles... We just keep it for at home. But our doubles did a really good job," she said.

Sadly, Arnett and Poehler announced their intention to divorce in 2014, which eventually became finalized in 2016.

"When you are a person going through a divorce, you feel incredibly alone, yet you are constantly reminded by society of how frequently divorce happens and how common it has become," Poehler wrote in her memoir, Yes Please. "You aren't allowed to feel special, but no one knows the specific ways you are in pain."

"Imagine spreading everything you care about on a blanket and then tossing the whole thing up in the air. The process of divorce is about loading that blanket, throwing it up, watching it all spin, and worrying what stuff will break when it lands," she continued.

But despite her sadness, Poehler also praised Arnett for being an excellent father to their two kids.

"I am proud of how my ex-husband Will and I have been taking care of our children," she wrote. "I am beyond grateful he is their father, and I don't think a ten-year marriage constitutes failure. That being said, getting a divorce really sucks."

5. John Travolta and Diana Hyland

Even though John Travolta and Diana Hyland didn't star as siblings in the movie,The Boy in the Plastic Bubble, playing a mother-son duo deserves to make this list.

Even though they had an 18 year age difference, Hyland was said to be the love of Travolta's life. They were together for seven months before she passed away from cancer at 41 years old.

"I picked out a house, and Diana and I were planning on moving in right after this movie. If she was alive, it is very possible I would have married her, Travolta admitted to PEOPLE.

"I have never been more in love with anyone in my life," he said about of his late girlfriend who died in his arms. "I thought I was in love before, but I wasn't. From the moment I met her I was attracted. We were like two maniacs talking all the time on the set of Bubble. After a month it became romantic."

"I gave her great joy the last months of her life," he added.  "I always feel she is with me"”I mean her intentions are. Diana always wanted the world for me in every possible way."

6. Katherine Heigl and Jason Behr

Before Katherine Heigl settled down with musician Josh Kelley, she was in a relationship with Jason Behr, her co-star on Roswell. While they played orphaned alien siblings on the show, it was clear they were dating in real life. They got together in 1999, and at one point they were rumored to engaged.

However, Heigl and Behr went their separate ways in 2001, only a year before the series came to an end.

7. Lauren Graham and Peter Krause

Even though Lauren Graham and Peter Krause had been friends for more than a decade before they starred as siblings on Parenthood. They began a romantic relationship in 2009 after Graham's Girlmore Girls co-star Kelly Bishop tried setting them up years ago.

"[Graham] doesn't remember this, but a long time ago, we were talking about the latest unworthy person. She is a very bright woman, and I always thought the guys she was going out with weren't smart enough for her because that's going to bore you after a while! Very quickly, actually. A lot of them weren't that successful, so that always makes the dynamic really awkward," Bishop said in an interview with Glamour.

"So we're talking about her latest problem and the fact that there's no one out there, and I say, 'You know, I've been watching this show I love called Six Feet Under, and there's this guy...' and she says, 'I know, Peter Krause.' And I said, "I think you two would make the greatest couple,'" Bishop continued.

She said, 'That's all very nice. We worked together years ago and there was some attraction, but he's married." I went, "Oh, OK, that's it!' All these years go by and I send her a birthday email"”'Happy birthday. Love, TV Mom'"”and she writes back in March and says, 'I didn't tell you this, but I've been seeing Peter Krause since December. We've been an item; we're going together.' I said, 'That is so fabulous!'"

While they're still together, Graham told Ellen DeGeneres in 2014 she and her beau have no plans to wed.

"I don't know. We are very happy as we are and I never have a good question for this answer," she said.

8. David Cassidy and Susan Dey

Back in the 70s, David Cassidy and Susan Dey starred as brother and sister on The Patridge Family, leading them the height of their fame.

Dey allegedly had a crush on Cassidy since the show first began, but he didn't immediately reciprocate her feelings. Even though they were said to only briefly dated while on set, their split was pretty acrimonious.

In Cassidy's autobiography, C'Mon Get Happy, he said "Susan lacked the slutty aspect of a female that I always found so attractive. She was sweetness and innocence, a good girl, and I couldn't think of her as anything but my sister," adding he only had a one-night stand with Dey after her relentless pursuit of him.

Once Dey heard of Cassidy's unflattering comments, despite his apologies, she refused to talk to him up to the time of his death.

9. Michael C. Hall and Jennifer Carpenter

Michael C. Hall and Jennifer Carpenter first met in 2006 after being cast as a brother and sister crime fighting duo on Dexter. After a year of dating, the twosome decided to tie the knot. She stayed by her Hall's side while he battled Hodgkin's lymphoma, and fans thought they had one of the few celebrity relationships that would last.

Unfortunately, the seemingly happy couple divorced in 2011, despite the fact they still shared screen time on the hit show.

"Our marriage didn't look like anyone else's, and our divorce didn't either, so...I said it before, just because the marriage ended doesn't mean the love did," Carpenter replied, her voice breaking. "I'm crying. It's an awkward thing to talk about your personal life in front of a bunch of strangers, but there's nothing but love and respect between us. Nothing," Carpenter said at PaleyFest Dexter Fall Farewell event.

10. Matthew Broderick and Jennifer Grey

While you might remember Jennifer Grey as Matthew Broderick's little sister in Ferris Bueller's Day Off, it's more likely you remember her infamous car accident in 1987.

She and Broderick, who had been dating at the time, were on vacation in Northern Ireland when their car collided with another vehicle. Although Broderick was injured during the crash, and Grey still suffers chronic pain, the mother and daughter in the other car were dead.

"One minute we're going down the road and music is playing, and the next minute ... it's all different," Grey told PEOPLE. "I couldn't be fearless after that."

Less than a week later, Dirty Dancing would appear in theaters, which ended up being Grey's most iconic movie to date.

"I became America's sweetheart within five days of the accident," she said. "The juxtaposition of that deep sorrow, the survivor's guilt ... and then being celebrated as the new big thing just didn't jibe. It didn't feel good to be the toast of the town."

While the pair eventually broke up, they went on to live happy lives with Sarah Jessica Parker and Clark Gregg respectively.
