Celebrity life is messy, in case you didn't notice. And these famous love triangles didn't help anything either.
Although honestly, I don't feel bad for any of them. Welcome to Hollywood!
1. Kendall Jenner, Blake Griffin, and Blake Griffin's Ex-Fiancée
Talk about awkward. Jenner's romance with Griffin caused his ex-fiancée to file a lawsuit against him, claiming he cares more about dating a celebrity than taking care of his kids.
2. Niall Horan, Ed Sheeran, and Ellie Goulding
Goulding and Sheeran were rumored to be a thing in 2013 after being spotted holding hands.
Then the ginger singer released a song called "Don't" which is about a relationship with a fellow singer that ended with him getting cheated on...with, guess who?
One Direction's Niall Horan.
Nothing was ever confirmed...but it also was never denied.
3. Selena Gomez, The Weeknd, and Bella Hadid
The Weeknd...Mr. Weeknd? I don't know. Anyway, he was dating Bella Hadid for almost two years until November of 2016. Then in January of 2017 he started dating Gomez.
There was a lot of alleged drama between them all, because it's Hollywood and why wouldn't there be?
4. Selena Gomez, The Weeknd, and Justin Bieber
After her split with Mr. Knd (I really don't know how to refer to him), Gomez cuddled up with her former love Justin Bieber.
It didn't go over well with The Weeknd, who wrote lyrics about how he almost gave her a kidney.
"I said I didn't feel nothing baby, but I lied / I almost cut a piece of myself for your life," he sings. "Guess I was just another pit stop / Til you made up your mind / You just wasted my time."
5. Aaron Carter, Lindsay Lohan, and Hilary Duff
If this isn't a blast from the past, I don't know what is. Carter and Duff dated for a few months until Carter got "bored" and began dating Lohan.
Instead of blaming the obvious choice here, which is Carter, the girls blamed each other.
In 2015, Carter tweeted that Duff was the "love of his life" who he "lost forever" and that he "will spend the rest of my life trying to better myself to get back to her."
Duff called these declarations "ridiculous." Same, girl.
6. Justin Bieber, Orlando Bloom, and Miranda Kerr
After rumors swirled that Kerr cheated on her then-husband Bloom with Justin Bieber, things got ugly.
While in Ibiza, Bloom and Bieber ran into each other and Bloom threw a chair at Bieber before trying to punch him.
The next day, Bieber posted a picture of Kerr on Instagram. A couple years later, Bloom cozied up with Gomez at a club.
There are no winners here, only childish men who have way too much time on their hands.
7. Joe Jonas, Taylor Swift, and Gigi Hadid
Jonas famously dumped Swift via telephone, and she's been bitter ever since. Hadid, a member of Swift's "squad" then started dating Jonas a few years later, and it reportedly cause a ton of drama.
But honestly, what doesn't cause drama when Swift is involved?
8. Taylor Swift, Katy Perry, and John Mayer
The feud between Swift and Perry runs deep, but it certainly didn't help anything when Perry started dating Swift's ex, John Mayer.
Did Perry not listen to "Dear John?" Swift sees it all now that he's gone. Don't you think she was too young to be messed with? The girl in the dress cried the whole way hooooommmmeeeeee!
9. Kylie Jenner, Blac Chyna, Tyga...and weirdly also Rob Kardashian
This...this is just a giant mess, honestly. Tyga was dating Blac Chyna, and they had a son named King Cairo together. Then they broke up, and Tyga started dating Kylie, who was only 17 at the time.
Then, Chyna started dating Rob and the two had a kid together. But there was apparently drama between Kylie and Chyna that was causing problems.
Didn't matter, though, because Chyna and Rob had a kid.
Then Tyga and Kylie broke up and she got pregnant with Travis Scott's kid, but Tyga said he thought the kid was his (it isn't).
Just a little sloppy, that's all.
