Lea Michele & Naya Rivera
These Glee co-stars were rivals both on and offscreen, and Naya spilled all the tea in her 2016 memoir. One of the Glee writers had described the actresses as two sides of the same battery, strong-willed, and competitive. It wasn't a good mix, and when Naya's character started to get more screen-time, that didn't sit well with Lea, the alleged "star."

Paris Hilton & Nicole Richie
Childhood best friends-turned pop culture sensations gained fame through their reality TV show The Simple Life.

David Letterman & Jay Leno
When Johnny Carson announced he was leaving NBC 's "The Tonight Show" in 1992, fans believed the obvious replacement would be David Letterman, who hosted "Late Night With David Letterman" on the same network. But instead, NBC gave the show to Jay Leno, a comic who had appeared as a guest on Letterman's show multiple times.

But Rivers denied that was ever the case.

Naomi Campbell & Tyra Banks
Back in the early '90s, Tyra Banks admits she was initially pitted against supermodel Naomi Campbell when she first started in the modeling industry.

Apparently, the entire lead cast of the hit TV show couldn’t set their differences aside and get along during filming.

Nobody was happy with the order the cast was lined up for the photo, and god forbid someone got to choose their outfit before someone else!
