15 Celebrity Couples You Didn't Know Had Kids Together

ABC News / People

It's hard to keep up with every celebrity's personal life. It seems like one minute they're dating one celebrity and the next they're dating another.

And some of these relationships are pretty low-key, so we don't hear much about it.

For example, Kate Hudson recently announced she's pregnant with her third child. I didn't even know she had a child!

Turns out, before Hudson met her musician boyfriend Danny Fujikawa, she was married to Chris Robinson, who was the singer of the rock and roll band The Black Crowes.

They were married for seven years and had one child together, Ryder, in 2004. When they split up, Hudson had a child with her boyfriend Matt Bellamy, an English musician, in 2011.

If that's news to you, these next celebrity couples who share a child together will surprise you even more...

1. Tom Hardy and Charlotte Riley

Tom Hardy rose to fame in the U.S. after appearing in hit movies like Inception, The Dark Night Rises, and Mad Max: Fury Road.

I'm sure most of us have wondered about this Hollywood heartthrob's love history, and you won't be disappointed.

Like many actors who have fallen in love on set, Tom Hardy met English actress Charlotte Riley when filming the 2009 UK TV series Wuthering Heights.

This was the time the actor was starting to make a name for himself in America, so not many people noticed when the couple welcomed their first child, Louis Thomas Hardy, in 2015.

2. Joseph Gordon-Levitt and Tasha McCauley

You probably could have never imagined that the baby-faced Angels In The Outfield actor would one day have a child of his own. In fact, he has two!

His wife, Tasha McCauley, is not a Hollywood celebrity, but she's quite well-known in her realm of expertise, which is robotics and business administration.

She's not a big fan of the limelight and tries to keep her personal life as private as possible. What we do know is that they share two sons, but they're so secretive we have no idea what their names are!  

3. Jeremy Renner and Sonni Pacheco

You may know Jeremy Renner for his role as Hawkeye in The Avengers or as Hansel in Hansel & Gretel: Witch Hunters, but what most people don't know is that he married a well-known Canadian actress for a short time.

Sonnie Pacheco and Renner tied the knot in 2014 when Pacheco gave birth to a baby girl, Ava Berlin, a year before.

Less than a year later, Pacheco filed for divorce.

4. Megan Fox and Brian Austin Green

About a decade ago, Megan Fox was everywhere on the big screen and magazine covers, but that was all before she had children with prominent actor Brian Austin Green.

They share three young kids together: Noah, Bodhi, and Journey.

The couple have had their ups and down, though. They got engaged in 2006, called it off in 2009, and got engaged again a year later. They got married in 2010, but Megan filed for divorce in 2015.

When she heard she was expecting her third child, Journey, they got back together.

5. Norman Reedus and Helena Christensen

The Walking Dead star fell in love with former Miss Universe winner Helena Christensen almost two decades ago. They were together for five years, until they decided to part ways.  

They welcomed their first child, Mingus Lucien Reedus, in 1999 and still share joint custody. After all these years, both of them still have one child.

These next celebrity couples are even more surprising...

6. Sacha Baron Cohen and Isla Fisher

These two comedic actors have found a way to start a family without much media attention. They met more than a 15 years ago, and are still head-over-heels for each other.

Their first daughter, Olive, was born in 2007 before the Borat actor and Fisher tied the knot.

They welcomed their second daughter, Elula, in 2010 and their first son, Montgomery, in 2015.

7. Kate Beckinsale and Michael Sheen

As one of the stars of the Hollywood blockbuster, Pearl Harbor, Kate Beckinsale has achieved quite the fame over the past couple decades.

If you're not very familiar with Michael Sheen (who has no relation to the actor Charlie Sheen), he became famous over his role in The Twilight Saga and Nocturnal Animals.

They were together for almost a decade, and welcomed their daughter, Lily, in 1999. They split in 2003, but are still on "friendly terms."

While they've both gone on to date different people, they still have one child.

8. Adele and Simon Konecki

The renowned English singer-songwriter who has more accolades than we can remember received a lot of media attention when she welcomed her first son, Angelo, in 2012.

Most of us who had no clue that Adele was in a relationship were even more confused when she gave her son her own last name (Adkins).

A few months before she gave birth, she revealed that she and Simon Konecki, a charity entrepreneur, were having a baby.

According to reports, the couple tied the knot in 2016.

9. Dennis Quaid and Meg Ryan

Hollywood romances from before the turn of the century just don't garner a lot of media attention anymore.

There's much more juicy stuff to report on, which is why barely anyone remembers that romantic-comedy star Meg Ryan and Dennis Quaid were a thing.

The couple got married in 1991, and at the time they received a lot of media attention, but everyone forgot about their relationship when they divorced in 2000.

What many people also forgot is that they share a son, Jack, who was born in 1992.

Jack has followed his parent's footsteps and has appeared in the hit movie series The Hunger Games.

10. Eddie Murphy and Melanie Brown

Eddie Murphy has a total of nine children with five different celebrity mothers, but it's his child with Spice Girls member Mel B that resulted in a paternity battle.

A DNA test proved that Murphy is in fact the father of Angel, who was born in 2007. Brown also has two other daughters with two different men.

Some of the biggest names in Hollywood have dated and we had no clue...

11. James Cameron and Linda Hamilton

If you don't recognize James Cameron's face or name, you've definitely heard of his movies. The Canadian filmmaker is well-known worldwide for bringing Avatar, Titanic, and The Terminator to the big screen.

Shortly after Cameron called it quits with director Kathryn Bigelow, he started dating Sarah Connor actress Linda Hamilton.

They met on the set of The Terminator and fell in love. They married in 1997, but unfortunately their love didn't last for too long.

Hamilton has described her relationship with the famous filmmaker as "terrible." She said the only good thing that happened in the couple years they were together was their daughter, Josephine.

12. Clint Eastwood and Frances Fisher

The Western actor has had a lot of women in his life, which is why it's nearly impossible to keep up with all of them - unless you've watched their reality series show Mrs. Eastwood & Company.

Frances Fisher, who you probably recognize from Titanic, met Eastwood on the set of Pink Cadillac in the late '80s.

They co-starred in the 1992 movie Unforgiven, and a year later Fisher gave birth to her first daughter, Francesca.

Three years later, they ended their relationship, which left Fisher heartbroken for years.

13. Tom Brady and Bridget Moynahan

It's practically common knowledge that Tom Brady and Brazilian supermodel Gisele B√ľndchen are married. The couple also share a boy and a girl together, and their pictures are everywhere on the internet.

But before Brady fell in love with the Victoria's Secret model, he dated another model: Bridget Moynahan.

Only three months after they broke up, Moynahan learned she was pregnant with Brady's son. She gave birth to John in 2007, and the former couple have kept in contact for the sake of their son.

14. Laurie Metcalf and Jeff Perry

Laurie Metcalf is best known for her role as Jackie Harris on the hit series Roseanne.

Years before Metcalf became one of the most beloved sisters on television, she and Jeff Perry, who plays the president's confidant on Scandal, had a daughter, Zoe, in 1984.

They were married for nearly a decade, between 1983 and 1992.

Not many people remember these two dating at the time because we were more concerned with Jackie Harris's relationships on the sitcom.

15. Heath Ledger and Michelle Williams

It's been a decade since Heath Ledger died of an accidental drug overdose, but what many of us have forgotten is that he left us his daughter, Matilda.

Heath met Matilda's mother, Michelle Williams, while filming Brokeback Mountain in 2004.

The Dawson's Creek actress and The Dark Knight actor welcomed their daughter a year later, but split in 2007.
