Are Ariana and Jennette feuding?

Ugh, this is the saddest thing ever! After Jennette McCurdy wrote a super long essay about a "fake friend" who's " a leech for drama and gossip," all signs point to the fact that she was talking about her Sam and Cat co-star and former BFF, Ariana Grande. The good news? If the post was about Ariana, she refuses to keep the drama going. "Everytime you're faced with something ugly, focus on something beautiful," Ariana tweeted just two days after Jennette's essay. "What you focus on expands only you can change your reality." So true!
