Sam & Cat stars Ariana Grande and Jennette McCurdy seem like they're the best of friends, but after Jennette not only skipped out on the 2014 Kids' Choice Awards but unfollowed Ari on both Instagram and Twitter, everyone knew something was up and the star had some major explaining to do.

Even though Sam & Cat won "Favorite TV Show" and Jennette was nominated for "Favorite TV Actress" (going up against Ariana for the same title), she had a pretty big reason why she didn't want to go to the show and got on Twitter to give her fans some details why.

"A lot of you guys are asking why I didn’t attend the KCAs…. I wish I could explain everything as thoroughly as I would like to, but unfortunately a simpler explanation is all I can write," Jennette tweeted. "I was put in an uncomfortable, compromising, unfair situation (many of you have guessed what it is) and I had to look out for me. I chose to not go because sticking up for what is right and what is fair is what my mom taught me is ALWAYS the most important thing. I want to thank those of you who have reached out with kind words of support, McCurdians and Arianators alike. No matter who or what you support, I believe in supporting fairness first. If you have done that, thank you.”

Although fans thought she was talking about her racy leaked pictures at first, the reason quickly went in another direction after seeing she unfollowed Ariana on all social media accounts. Fans are assuming it's because Nickelodeon put them up against each other for "Favorite TV Actress," but no further details have been revealed.

Ariana must have seen all of Jennette's tweets after the awards show, because the star seemed pretty upset — she couldn't even fall asleep.
