Floyd Mayweather celebrates 31st birthday ... with Keyshia Coles!

Well, it IS February so maybe cupid is working overtime.




Floyd Mayweather celebrated his 31st birthday at Jet Nightclub at the Mirage this past Monday night in Vegas.

One question: why?


Apparently, partying with your mama at the club is the new hotness! I'm not mad ...

Dude is really making his publicity rounds these days. Should be interesting to see where else and who else he pops up at or with in the next few months before Wrestlemania (3/30) and the De La Hoya fight this fall.
