Is That Justin's Bieber? Check Out His Grammy Wardrobe Malfunction

On music's biggest night, the teen sensation forgot to zip up his pants before posing for pictures

When it comes to wardrobe malfunctions, Justin Bieber should never say never.

Sure, this one wasn't nearly as noticeable as the one that, say, another Justin had a hand in all those years ago, but this is the Biebs were talkin' about, so of course we have to bring it up.

Unfortunately, bringing it up is just what the teen sensation inadvertently forgot to do at the Grammys on Sunday evening and he wound up posing for pics backstage with his fly open.

Although, we'll definitely cut the guy some slack for such a slip. After all, his mind, like everyone else's, was probably preoccupied with trying to figure out  who the heck is Esperanza?
