Jeanette McCurdy and Ariana Grande's characters in the Nickelodeon show Sam & Cat were total opposites, but they were still BFFs. In real life though, things got catty when Ariana started to find success in her solo music career.

While they officially said the show had ended due to a drop in the ratings, there were stories of salary disputes between the two and Jeanette wrote an internet rant about breaking up with a friend. Jeanette also threw shade later on by writing about a character named Gloriana who flaunted her singing talents.

Ariana's feud with Jeanette wasn't the first time Nickelodeon had to cancel a show thanks to her drama.
