Big Stars + Little Cars = Clown Time

So a brunette (Brooke Shields), a blonde (Kim Raver) and an ex-sitcom star (Matthew Perry) walk out of an Upper East Side karaoke bar ...

Confusion (and clown car-ishness) ensued, as the "Cashmere Mafia" "Lipstick Jungle" cast sang their lungs out at Iggy's -- then had to play musical car seats to get downtown.

Unbelievably, Perry was convinced to give up his cab seat to "Studio 60 on the Sunset Strip" co-star, Timothy Busfield. Matt got the last laugh -- check out who he went home with!
