They were doing more than just brawling at the Las Vegas pool parties this weekend.
Diddy's chlorinated event, which took place Saturday afternoon at the SLS Hotel & Casino's Foxtail Pool Club, took it back to the '90s with a rendition of the Notorious B.I.G. classic 'Mo Money Mo Problems'.
This wasn't a hologram situation, so there was obviously no Big. But Puffy brought Ma$e along, and Lil Wayne also jumped on stage as a special guest.
Weezy did two-fisters one better during his performance: he had two drinks in one hand so he could use his other to smoke.
The sound qaulity is a bit shaky, but it certainly looks like a good time was had by all.
