Demi Moore is down in Miami this week for Art Basel, hanging out with her post-Ashton catch Vito Schnabel. Like any normal American getting over an embarrassing, trying divorce, Moore was seen last night partying at Alex Rodriguez's house with Lenny Kravitz. At the party she was just being a very cool, totally non-embarrassing mom, who just so happened to be putting on an unsolicited audition for the Twerk Team, YouTube's foremost ass-shaking troupe.

There was no word as to why no one else was dancing, or why Kravitz looked incredibly non-plussed by the whole situation, or which song was playing. Probably "Rack City" (or "We Are Never Ever Getting Back Together"), though. Oh, and there's more where that came from.

UPDATE: The New York Post claims that earlier in the night, Demi picked up a stray cat and brought it to dinner "as her date." The cat reportedly sat on her lap throughout the meal. Since the cat does not appear to have been present at the actress' twerk-a-thon, we can only assume that it faked a cellphone call to duck out early.
