Did Demi diss Miley and Ariana?

Demi Lovato was just catching up on her twitter scoop when she saw something crazy! "What's Demi a Lavender and why are people tweeting me that?" she wrote. It turns out, the tweets referred to a post written by a "fan" who Demi by the last name Lavender instead of Lovato. The writer claimed that she ran into Demi at the airport on her way to Cancun and that Demi dissed both Miley Cyrus and Ariana Grande. When Demi found out about the false post, she cleared things up quickly. "I wish I was on my way to Cancun," she joked. "But not as much as I wish my last name was lavender..." Ha!
