What happened to Justin's pants?
File this one under: huh?

Who knew teen superstar Justin Bieber was such good friends with junior middleweight champion, Floyd Mayweather? The Biebs was spotted last night in Las Vegas cheering on Floyd and his Money Team with the likes of 50 Cent and Lil’ Wayne. And when Floyd was announced as the winner, Justin jumped into the ring and joined in the cheering. 

Too bad there weren’t any puppies in the ring for Justin to be sexy with. Side note: I love random celebrity friendships. And this one seems pretty legit. Justin was even Tweeting to Floyd before the fight started.

Well, you learn something new about celebrities everyday. Also, doesn’t this kind of sound like a set up for a joke? “Justin Bieber, 50 Cent & Lil’ Wayne walk into a boxing ring…” How would you finish it?
