Rihanna and Katy Perry

Once upon a time, famed singers Katy Perry and Rihanna were the best of friends. They were seen going on adventures together and often gave each other credit for their individual successes. When Rihanna returned to Chris Brown after the incident between them, Perry was not very happy about it.

Perry admitted that she no longer reached out to Rihanna after this happened. When controversies arose over Perry dating John Mayer after ending her marriage with Russell Brand, Rihanna threw shade at her former friend. Some reports suggest that even at present, the two women remain cold towards each other.

Paris Hilton and Kim Kardashian, Nicole Richie, and Lindsay Lohan

The degree to which Paris Hilton changes besties like she changes designer clothes is astounding. This reputation started when she burned bridges with her childhood friend Nicole Richie. She never talked about what caused the split, however. Next, she and Kim Kardashian also chummed up while the latter worked for her as a personal assistant.

Kardashian was even featured on Simple Life. This friendship wouldn’t last either and talk came out that it’s because Kardashian couldn’t get enough of Hilton’s VIP life. Lindsay Lohan was also often seen in parties with Hilton before they ended up on each other’s bad side. Dramatic, right?

Lauren Conrad and Heidi Montag

The Hills stars Heidi Montag and Lauren Conrad were first seen on the MTV reality show, which helped them rise to fame. Things began going downhill (pun intended!) for the besties after Heidi Montag and her partner Spencer Pratt reportedly gossiped about the controversial video involving Conrad and her partner.

PerezHilton.com reported that the issue blew up to such an extreme degree that both women had to face each other on set, following a heated argument that was caught on camera during the third season of The Hills. Conrad refuted the report through her website, but the two never mended their friendship after everything that happened.

Kenan Thompson and Kel Mitchell

Best friends on-screen and off-screen Kenan Thompson and Kel Mitchell were big names in the ‘90s comedy scene. However, after they released their 1997 film The Good Burger, the duo went their separate ways. Mitchell said to TMZ that Thompson wanted to pursue a solo career. To his credit, Mitchell respected his friend’s decision.

He said they haven’t spoken to each other in so long that he doesn’t think a reunion could happen anytime soon. Fortunately and much to the delight of their fans, Thompson did eventually agree to do Good Burger on The Tonight Show with Jimmy Fallon in 2015.

Gwyneth Paltrow and Madonna

Superstar best friends Gwyneth Paltrow and Madonna used to be each other’s main-girl. They even worked with the same physical trainer, Tracey Anderson. When Anderson ended up facing issues, Madonna stopped working with him and urged Paltrow to do the same. However, the actress refused to.

Writing in a GOOP Newsletter, Paltrow talked about Madonna being an “insufferable” friend. Years have passed, but if reports are true, the two blondes still have deep-seated hate for each other. This came to a head during the Met Gala where Paltrow allegedly accused Madonna of trying to take all the attention from Beyonce.

Jay-Z and Kanye West

World-famous rappers Jay-Z and Kanye West used to be the best of friends. However, it wasn’t long before they shook the hip-hop world following their notorious split. The degree of controversy was quite high when this happened. Channel 4 even made an entire documentary about the end of their friendship.

Apparently, when West and his wife Kim Kardashian got robbed in Europe, Jay-Z did not reach out. West felt abandoned by his brother, especially after going through such a troubling experience. He was even hospitalized for trauma issues after the incident. He threw shade at Jay-Z in a press interview. Jay-Z returned the same favor through one of his hit songs.

Katy Perry and Taylor Swift

When Taylor Swift’s song Bad Blood came out, the entire world started speculating on what it might be about. A lot of them were convinced that it was dedicated to her ex-BFF Katy Perry. The two pop sensations used to be joined at the hip, after all.

Swift tells the media that the reason for their distance is because Perry had allegedly tried to take her staff from her, but some of their fans had other ideas. Many hypothesize that John Mayer could be the reason why the two are no longer friends. To their credit, though, these two have since patched things up.

Britney Spears and Christina Aguilera

Britney Spears and Christina Aguilera knew each long before they were both considered to be pop princesses. They met on the set of The Mickey Mouse Club and maintained a close friendship even after they both made a name for themselves.

When Blender reported that Aguilera called Spears a “lost girl” in 2003, Spears did not take it lightly. She called Aguilera rude and fake. Perhaps this is also the reason why they were constantly pitted against each other. The investments both stars made to get to where they are right now probably did not leave room for fake friends and shallow friendships.

Taylor Swift and Emma Stone

Award-winning celebrities Taylor Swift and Emma Stone used to be BFFs. They were constantly seen hanging out whether in cafes, on leisure trips, and even on set. As times changed and both of them got busier, their friendship seemed to dissolve and just evaporate completely.

Not knowing where the electricity between the two comes from, we’re all hoping that it’s all just a case of drifting apart. With their equally busy lives and their highly fruitful and public careers, both women might have found it hard to keep up with their usual late-night fro-yo dates. Time is an important investment in any relationship, after all.

Demi Lovato and Miley Cyrus

Many of their fans loved the friendship between Demi Lovato and Miley Cyrus. Their relationship blossomed during their time together at Disney. The two had a tight bond and they often spoke affectionately about the other.

Lovato once told Seventeen magazine that because she and Cyrus both have strong personalities, they tend to clash to a degree. Sometimes, even swearing to never be friends again! However, they would often make peace just a few days after. After 2014, however, it seems like the two never got the change to reconcile after a spat since Lovato didn’t talk about her fellow Disney star in the same way anymore.
