Miley Cyrus: Headed for a Breakdown?

Miley Cyrus is putting on a happy face these days, one often seen slobbering all over Avan Jogia.

But friends of the singer tell Hollywood Life that she's actually suffering a lot in the face of her parents' divorce, as they fear she's headed down a Demi Lovato-like, destructive path.

“Miley is trying to be strong going through her parents' breakup and she loves them both,” a friend claims. “Everyone is reading into each of her every moves, like when she goes out with her mom and no one sees her dad. It’s pushing her buttons.”With filming on the film LOL underway, this source says Cyrus is "trying to focus on her new movie." However:

"Some of us are worried about her. She’s putting on a brave face, but she seems tired and stressed.”
