Think you had the hottest pool party this weekend? WRONG!

Hip-Hop mogul Diddy kicked off the Labor Day Weekend 2010 festivities by hosting a huge pool party at the Wet Republic pool at the MGM Grand Hotel & Casino Saturday afternoon (Sep 4) in Las Vegas, NV.

Check out a few pics of Diddy partying it up (with PLENTY of Ciroc to go around) in Vegas.
