Demi Lovato Disses Justin Bieber’s On Again Girlfriend Selena Gomez – Explains Why She Unfollowed ‘Come And Get It’ Singer (VIDEO)

BFFs no more? Demi Lovato finally revealed why she unfollowed Selena Gomez on Twitter. Find out what she said on "Watch What Happens Live!"

The former Disney star played "Plead the Fifth" with host Andy Cohen.

"You recently unfollowed your BFF Selena Gomez on Twitter. So much speculation about this. Can you tell us why?" Cohen asked the star.

"I Plead the Sixth...if that's in the game," Lovato replied.

He continued to pry, asking if fans were "reading too much" into the situation.

"I think it's just one of those things where people changed and people grow apart," the "Neon Lights" songstress explained.

Lovato unfollowed Gomez last month, allegedly due to the never ending drama with on-again boyfriend Justin Bieber.

"Demi doesn't need any extra drama, she's learned from her own recovery to lose the people that bring her down and Selena is too much of a headache," a source told Hollywood Life at the time. The unfollowing of Selena is sending a message that Demi is pissed. She is sick of Selena's boy-who-cried-wolf mentality."
