Were you confused when Justin Bieber escorted Floyd Mayweather to the ring again before a fight on Saturday night? Us, too. It's the third time he has done it now, so it's getting a little bit weird. Those two obviously have some sort of bromance that we just don't understand. Then again, maybe we shouldn't be so creeped out by it, because there are tons of celebrities and athletes who have had bromances in the past. Bleacher Report just put together a list of some of them over here. Which one was the weirdest to you?
