AceShowbiz - Just like their characters on "Sam & Cat", Ariana Grande and Jennette McCurdy were best friends off-camera during the filming of the Nickelodeon show. Despite its popularity, the series was canceled after just one season in 2014, prompting speculations that there were tensions behind the scenes. Words were Jennette was paid less than Ariana, even though they had equal roles on the show. Ariana denied this, but Jennette seemed to confirm it by saying that Nickelodeon had put her in "an uncomfortable, compromising, unfair situation" and that she had to look out for herself. Adding fuel to the fire, the blonde actress unfollowed Ariana on social media.

A year later, Jennette admitted that they "butted heads at times but in a very sisterly way." Though she denied that they were feuding like it was reported, the former "iCarly" star once explained her fizzled relationship with the "Thank U, Next" songstress, "I just feel that, you know Ariana and I were and are extremely close and very like-minded in a lot of different ways and then, sorta as the show dissolved, everybody wanted to find some sort of hidden meaning in our relationship."
