Dating your friend's ex? For some, that's breaking the code and obviously a big no-no, but apparently, it happens all the time in Hollywood!
The amount of love triangles involving famous pals may surprise you, but we come across it time and time again. One of the most recent examples is our vampire-friendly trio Nikki Reed, Ian Somerhalder and Nina Dobrev. The blue-eyed hunk has been spotted getting cozy with the Twilight actress, who just so happens to be gal-pals with Somerhalder's former longtime girlfriend and Vampire Diaries co-star Nina Dobrev.
So we started to wonder...which other celebs have dated their bestie's ex? We were able to put together a list for your reading pleasure, and you may just see a few repeat names on there (Hi, Taylor Swift !).
Katy Perry/John Mayer/Taylor Swift: Music brought the guitar-strumming crooner Mayer and Swift together when she was only 19 years old. Things fizzled, and a few years later, Mayer found himself in a rollercoaster relationship with Perry, who is also pals with T.Swift.
Heather Locklear/Richie Sambora/Denise Richards: Talk about drama fo' yo mama! Locklear and Richards were the closest of friends, but after Heather and Richie's marriage went downhill around the same time as Denise and Charlie Sheen, things changed. Before you knew it, Richards and Sambora became an item.
Taylor Swift/Joe Jonas/Demi Lovato/Ashley Greene: Whoa now, here's a doozy! So let's break it down: Swift, who is pals with both Lovato and Greene, was the first of the lady trio to date the Jonas brother (back in 2008-ish). Shortly after, Joe became linked to Demi, and then after their split, dated Greene (and drama ensued).
Lindsay Lohan/Aaron Carter/Hilary Duff: This teen love affair was one for the books. More than a decade ago, Duff and Carter were an item. But that changed when the teen singer famously broke up with Duff amid speculation that he had hooked up with Lindsay Lohan who was also buddies with Hilary.
Drew Barrymore/Fabrizio Moretti/Kristen Wiig: There was surprisingly no bad blood here. In 2012, Barrymore opened up to Allure about her SNL bestie's relationship with her former long-time beau, Strokes drummer Fabrizio Moretti. "It all seems so wacky and incestuous, but that's kind of how life works," the actress explained. "It seems fitting that they would find each other. I was like, 'Right, of course, that makes perfect sense.'"
Taylor Swift/Harry Styles/Cara Delevingne: Swifty and Styles were once a canoodling pair, but after their split, Harry began to hang out with Delevingne quite frequently. Funny enough, Taylor and Cara weren't exactly best buds at the time, but they became close after Harry was in the picture.
Elizabeth Taylor/Eddie Fisher/Debbie Reynolds: This love triangle became one of Hollywood's most scandalous stories. After her third husband, Mike Todd, died in an airplane crash, Taylor sought comfort in the arms of her good friend Debbie Reynolds' husband, Eddie Fisher. He ended up leaving Reynolds to be with Elizabeth. While that would usually cause any friendship to end forever, Reynolds and Taylor rekindled their kinship years later.
"Elizabeth and I were good friends when we were young—17," Reynolds once told The Huffington Post. "And then when we got older and Eddie [Fisher] left with Elizabeth, things changed, of course. But we wound up to be very good friends again, and laughed about it. Elizabeth was a very strong, powerful woman. When she saw something that she wanted, she got it. And that just happened to be my husband."
Miley Cyrus/Nick Jonas/Selena Gomez: Nick and Miley were (and for some, still are) the dreamy teen couple of its time. When that relationship came to an end, Jonas and Selena began to date, but it reportedly fizzled because of issues with his ex-girlfriend. We'd love to say Cyrus and Gomez have since reconciled, but we can't.
Kate Hudson/Alex Rodriguez/Cameron Diaz: These blond bombshells and buddies were reportedly in a bitter feud after Diaz pursued a romantic relationship with the baseball player after Kate's fling with him fizzled.
