Jennette McCurdy of “iCarly” and Ariana Grande of “Victorious” (and later pop music superstardom) collaborated on the spinoff series “Sam & Cat,” but their friendship turned into a feud faster than you can say “Thank U, Next.” The drama first began due to a rumor about Grande’s team and McCurdy.

A source alleged that Grande’s team didn’t like that McCurdy was "getting drunk and hitting strip clubs,” and wanted her removed from “Sam & Cat.” McCurdy’s image was damaged by the rumor, and she skipped out on attending the 2014 Kids Choice Awards, where Grande won “Favorite TV Actress.”

Just days after the awards show, TMZ reported that McCurdy had been absent because “Grande [made] WAY MORE money than her and she'[d] been trying to renegotiate her deal.” Grande denied the rumor and said she has always been about equality, but two months later, McCurdy fired shots of her own.

McCurdy wrote an open letter on TwitLonger to a mysterious soon-to-be-ex friend, saying, “I might possibly be the worst version of myself when I'm around you… I am officially dropping you as a friend.” Fans assumed McCurdy’s target was Grande, and a few weeks later, “Sam & Cat” was canceled.

McCurdy’s 2014 web series “What's Next For Sarah?” seemingly shaded Grande through a mocking character named Gloriana. However, in 2016, McCurdy appeared in a video jamming to Grande’s hit song “Into You,” implying that the two may have ended their beef, or at least moved on from it.
