The biggest celebrity friendship breakups

Paris Hilton and Lindsay Lohan also fell out and still throw shade at each other to this day.

Paris Hilton and Lindsay Lohan were fast friends in the early 2000s and partied in Los Angeles together on a regular basis. However, that all came to a swift halt in May 2006 after Hilton was filmed laughing while her friend Brandon Davis made disparaging comments about Lohan to the paparazzi. 

According to E! Online, Hilton's publicist said it was "unfair to characterize Brandon's statements as being reflective of Paris' feelings about Lindsay." Davis later apologized for his comments, but the damage had seemingly already been done. 

In November that year, Lohan was filmed calling Hilton the C-word on-camera, then immediately denying that she made the comment. A week later, Lohan alleged that Hilton had injured her arm at a party, saying, "It hurts and it's not OK. I'm sorry that everyone thinks I'm crazy. I'm not; I'm just trying to act."

The pair appeared to be back on good terms when they were spotted out partying with Britney Spears a day later. However, Hilton later said that Lohan "wasn't invited" to join her and Spears that night. Over the years, their friendship weathered multiple ups and downs, but they appear to no longer be on speaking terms. 

In a 2019 episode of "Watch What Happens Live," Hilton told host Andy Cohen that Lohan was "beyond," "lame," and "embarrassing." A week later, Lohan posted a throwback photo of her and Hilton with "#Beyond." She later added to the caption, congratulating her on the release of her new single, "Best Friend's A**."

Kim Kardashian and Blac Chyna were once friends, but now the former "Rob & Chyna" star is suing her for defamation.

Kim Kardashian and Blac Chyna, whose given name is Angela Renée White, were close friends before Kim's younger sister Kylie Jenner began dating Tyga, Blac Chyna's ex-boyfriend and the father of her eldest child. 

"I understand that Kylie dating Tyga completely broke Chyna's heart. I feel for her in that situation," Kardashian said on "Keeping Up With the Kardashians" in 2016. "Was it uncomfortable for me when Kylie and Tyga started to date? Absolutely, because Chyna was my friend."

The pair appeared to halfheartedly reconcile after Kim's brother, Rob Kardashian, began dating Chyna in 2016. Jenner also smoothed things over with Chyna, and the family was on good terms with the model. Chyna and Kardashian even landed their own spinoff show, "Rob & Chyna," which documented their relationship and life with their daughter, Dream.

However, their relationship turned sour after Rob Kardashian and Blac Chyna split. "Rob & Chyna" was later canceled after one season on the air.

In 2017, Chyna claimed in a defamation lawsuit that it was the Kardashian family's decision to end their show. She is claiming assault, battery, domestic violence, defamation, and interference with prospective economic relations in the suit.

"Chyna also proved that, although Kris Jenner was the ringleader for the plot to get Season 2 of 'Rob & Chyna' canceled, Kim Kardashian West, Khloé Kardashian, and Kylie Jenner each separately defamed and intentionally interfered with Chyna's contract for Season 2 — so all three daughters face a trial by jury for their illegal conduct against Chyna," Lynne Ciani, Chyna's attorney, told Insider in a statement. 

The family has denied the allegations, and Rob Kardashian has denied assaulting her.

The trial will start in October, but it's safe to say these two former friends won't be making up any time soon.

Selena Gomez and Demi Lovato met when they were kids, but their friendship has been through ups and downs.

Selena Gomez and Demi Lovato met on the set of "Barney & Friends" in 2002, and there have been many ups and downs in the two decades since.

"Very early on, you could just tell, they clicked," Fred Holmes, the show's director at the time, told International Business Times in 2017. "Certain kids got along with other kids and they were just two of those that really clicked. They were pretty inseparable and ate lunch together and all those types of things."

Over the years, the pair became practically inseparable as their acting and music careers took off on the Disney Channel. In 2009, they even teamed up to film "Princess Protection Program." However, a year later, their relationship appeared to have shifted.

"We're both busy, and I wish the best for her," Lovato said during an interview with Girls Life in June 2010. "True friends don't let their friends or family be mean to you. If you can't trust somebody, you can't be friends with them."

However, the pair appeared to be on good terms for the next few years and supported each other's projects publicly. Then, when Lovato checked into rehab for disordered eating and struggles with self-harm in 2013, she and Gomez reconnected.

"Selena called me crying when I was in there. She was just so worried. And I was like, 'Look, I should be the one crying. It's all good.' She was so worried, and ever since then we've gotten closer," Lovato said during a 2013 interview with TelevisionetMusic.

Then, in August 2014, Lovato unfollowed Gomez on Twitter, but they appeared to reconcile yet again and in 2017 made an appearance together at the InStyle Awards in Los Angeles. However, in 2018, they both unfollowed each other on Instagram.

After Gomez publicly congratulated Lovato for her Grammy Awards performance of "Anyone" in 2020, following her overdose, Lovato said the two were "not friends."
