What is it about child stars that makes them so prone to controversy? Nickelodeon, which just cancelled its popular comedy series Sam & Cat, after rumors of off-screen drama and possibly, some leaked racy photos. The show starred Complex cover girl Ariana Grande and Jennette McCurdy, who's at the center of rumors about the show's demise.

The drama is focused around McCurdy, who's rumored to have complained that she was earning less than Grande, which Grande denied on Twitter. Also, shortly after McCurdy and NBA star Andre Drummond broke up, photos of her in lingerie were leaked to the public in April. In a not-too-vague statement, she insinuated that Drummond had leaked them (which he denied, of course).
