Is Miley Cyrus a little heartbreaker?  The New York Daily News is reporting that MyCy is trying to ditch current boyfriend Justin Gaston to get back with ex bf Nick Jonas; scan-dal!

Miley is currently spending time overseas so she bring the magic (and merchandise) of Hannah Montana to children all around the world.  We spotted Miley coming out of her hotel in a rather adorable ensemble in London this afternoon, the actress signed autographs for waiting fans.

MyCy maybe free of male distractions for now, but back in the States it's a different story.  A source tells the Daily News, Miley and Nick want to get back together,” our source tells us. “Because they’re working together [on a new video], they’ve been put in close proximity to each other. They’re now spending more and more time together, and they’re constantly on the phone.”

Nick and Miley did go on a "just friends" lunch date this month, so they are definitely not feuding.  The source even adds, “Miley was over at the Jonas house recently, and they were smooching. Nick’s parents have this rule that when a girl is over, the door has to be open, but that didn’t stop Nick and Miley from making out.”

Yeah, Justin and Miley are dunzo.  How sad for 20-year-old Justin to be dumped by teen queen Miley!  Maybe he can rebound with one of the Pussycat Dolls.
