The Mayweather vs. Mosely fight went down this weekend in Las Vegas and tons of celebs made it out for the big event.

Last night in Las Vegas Floyd “Money” Mayweather defeated “Sugar” Shane Mosley by unanimous decision improving to a perfect 41-0-0 with 25 KOs.

Chris Brown sang the National Anthem at the Shane Mosley/Floyd Mayweather fight in Las Vegas. I’m not against a man making a living but I don’t think this was a smart move on Mr. Brown’s part.
