Just like celebrity splits and divorces, celeb BFF breakups happen - sadly, sometimes even to our favorite dynamic duos. Take Madonna and Gwyneth Paltrow: While they famously bonded over their mutual love of healthy eating and British husbands, it appears the pair had a falling out several years back. According to US Weekly, things went downhill after Madonna split with Guy Ritchie (pre-Gwyneth's conscious uncoupling) and the two had less in common. Sources also told US Weekly, "Gwyneth can be jealous and competitive."[Photo: Splash News]
Kim Kardashian and Paris Hilton
Few fizzled friendships are quite as famous as Paris Hilton and Kim Kardashian's. While the two were joined at the hip for much of the mid-'00s, rumors have swirled that the friendship ended because Paris was jealous of Kim's rise to fame following the release of her sex tape and the beginning of Keeping Up With The Kardashians.

Selena Gomez and Demi Lovato
Anyone who grew up on Disney Channel knows of the practically-legendary friendship between Demi and Selena - but things started to turn sour when Selena began dating Justin Bieber and Demi wasn't such a huge fan of her BFF's new guy. In a 2015 interview with Complex, Lovato said of Bieber, "He’s actually a nice guy. I don’t really know him that well, but he seems to have grown up. He looks like he’s maturing. But, you know, when you’re young and you get older, you change and people change."

Katy Perry and Rihanna
While Katy Perry and Rihanna used to be besties (RiRi even threw Katy her bachelorette party before her marriage to Russell Brand), the two have seemingly drifted apart over the years - and sources have told Hollywood Life that Perry began distancing herself from Rihanna when she disapproved of her decision to get back together with Chris Brown several years ago.

Sarah Jessica Parker and Kim Cattrall
It's widely known that things got tense between former friends SJP and Kim Cattrall towards the end of Sex and the City. Apparently, the clash between them was caused by Cattrall's jealously over Parker's salary. SJP even told Marie Claire, "There are times when all of us have been sensitive and sometimes feelings get hurt." Uh-oh.

Paris Hilton and Nicole Richie
Paris Hilton's list of former BFFs isn't just limited to Kim Kardashian - but when it comes to Nicole Richie, the pair simply grew apart without any bad blood. Nicole told US Weekly, "The short answer to this is, I haven’t spoken to her in a while, but we are very good friends. I love her and I love her family. I have a lot of respect for her."

Like many real-life friendships, former teen Disney stars Miley and Demi simply grew apart. Demi told the Boston radio station 103.3 AMP in a 2014 interview, "It's life and people change. I don't have anything in common with her anymore. I wish her the best."
