On Thursday night, Demi Lovato took a seat on the Watch What Happens Live couch (next to Jessica Alba, no less) to play host Andy Cohen's "Plead the Fifth" game, in which Cohen asked about her BFF-no-more, Selena Gomez.
"You recently unfollowed your BFF Selena Gomez on Twitter. So much speculation about this. Can you tell us why?" Cohen asked.
