Demi Lovato, 21, and Selena Gomez, 21, have seriously been friends for their entire lives. Their friendship began when they were child actors on Barney & Friends, but could their friendship be over after all this time? On July 2, Demi threw major shade with a Twitter post to an unnamed ex-friend, and we have reason to believe she’s talking about Selena! Click below to get the scoop.

Demi Lovato’s Selena Gomez Diss: ‘Bye Bitch’ Pic On Twitter — Are The Ex-BFFs Feuding?

It’s only been a few months since Selena thanked Demi during her acceptance speech for the Young Humanitarian Award from at Variety‘s unite4:humanity gala, and the two seem to be fighting already! Demi has always given Selena relationship advice and even helped intervene to get her into rehab, so it’s totally crazy that the two seem to be in a feud!

On July 2 Demi shocked us all when she unfollowed Selena on Twitter, but she didn’t stop there! Shortly after the unfollowing, she allegedly posted a tweet saying “Bye” with a photo collage reading “Swimming away,” “From your bullshit,” “Bye bitch.”

The alleged tweet has been taken down, but here’s a screenshot via OITND:

Are Demi Lovato and Selena Gomez feuding?!

Yesterday, Lovato unfollowed Gomez on Twitter, causing fans to wonder if there’s a rift in their friendship. But the drama doesn’t stop there.

Lovato allegedly tweeted a not-so-nice message that seems to be directed at Gomez if the former BFFs are indeed fighting. “Swimming away from the bulls–t bye bitch,” the 21-year-old “Neon Lights” singer allegedly posted on Twitter along with a graphic of her swimming in the ocean. Yikes—talk about shade!

If the mean tweet is real, Lovato has since deleted it (but there’s a screengrab of it still floating around the web). Lovato’s rep declined to comment on the topic.

Back in February opened up to E! News about her bestie, calling her “amazing.” “Selena, I’ve known her for 14 years and we’ve been best friends,” the former X Factor judge said. “I love her.”

And a few weeks before that, Lovato said of Gomez, “She’s doing really well right now and I’m really happy for her…We have an incredible friendship.”
