Jenny McCarthy impressed as she arrived at Gallery Nightclub in Planet Hollywood Resort and Casino in Las Vegas to celebrate Halloween and her 40th birthday. In case you were wondering, teh 40 year old MILFilicious cougar is on the market having broken up with Chicago Bears Bran Urlacher a few months back. Surprisingly between all the photos we’ve seen from this event there were no boobs popping out of that outfit. Really, that’s probably what most of you would expect given Jenny’s assets. Well, you can always Google for shots of her Playboy spreads from this year and from all the way back in 1993 (and that hairy crotch).
