Seeing as Justin Bieber made a hit song out of a simple question, "What Do You Mean?<br />," you'd think he'd be more straightforward about what's going on with him and Selena Gomez.<br />These two have been on and off, hot and cold and pretty much any expression that reflects a rocky relationship, for as long as they've been officially broken up.<br />But in recent weeks something seems to have changed.<br />Both pop stars caused tweens' hearts to beat through their chests at the end of November when video surfaced of the Biebs serenading Selena while out to dinner.<br />His song choice?<br />"My Girl."<br />Hmmm seems a little suspicious.<br />They would later slow dance to Lionel Richie's "Easy.<br />"But Tuesday night Justin made his fans' hearts skip a beat again when he randomly posted a throwback photo of him and Selena riding an ATV.
