Justin Bieber grabs fan's breast at meet and greet

justin-bieber-grabs-fans-boob.jpg Justin Bieber is clearly enjoying being newly single, judging by the grope-fest in this photo from a recent meet and greet in Miami! The photo clearly shows Justin smooching a female fan on the cheek -- and grabbing a handful of boob, while he's at it. Awkward.

(We've blurred her face, but to be fair, she doesn't look particularly dismayed by Justin getting all up in her business.)

Of course, it's possible Justin was going in for a hug and just... missed by a mile, so we'll cut him some slack. But he definitely wasn't on his best behavior in Miami. He bailed on fans at an event, and later was three hours late taking the stage at his concert. Though his handlers claimed he was sick, he was spotted riding his bike around the venue.

He hasn't had the best time lately, of course. Justin opened up to Billboard Magazine after his split from longtime love Selena Gomez, saying, "I'm not in the happiest place that I've ever been. I'm trying to get through what I'm going through. Like I said, I have my really close friends to cheer me up and keep me going."
