I believe that the original intent of this weekend was one of Donald Driver’s charity events and it turned into a celebration of Katherine’s birthday and DWTS reunion. What I notice about these pictures is that it appears to be Derek and his harem…and he occasionally lets other guys visit for a minute. In any case, it looks like they’re having a great time!! A couple stories about their parties can be found at Haute Living and Tipsy Diaries – that’s where the second picture came from. The others were tweeted by Derek, Maria, Katherine and Cheryl – very hard to tell who started the tweeting.
