David Copperfield- magician
Paul Gleason-played the principal in The Breakfast Club
Julie McCullough-played Kirk Cameron's girlfriend on Growing Pains
Cynthia Rhodes-played Penny in Dirty Dancing (the tall blonde)
The Rock-wrestler He was buying sunglasses at,well, the SUNGLASS hut
Jean Claude Van Damme- in a bar in New Orleans (kinduva jerk though)

There's been a couple more but I can't remember right now who they were. Not really big stars but it makes for an interesting thread I guess.
