Jennifer Lopez Makes Surprise Appearance  6/27/06

Jennifer Lopez thrilled crowds at last weekend's (24-25JUN06) Gay Pride Pier Dance in New York City by appearing as a surprise performer.

The Jenny From the Block singer appeared with some of the dancers from her new MTV reality show Moves.

The show, shot in Los Angeles, gives a behind-the-scenes look at the lives of real dancers trying to get their big break, all selected by Lopez herself.

Lopez took the stage at 10:30pm with the dancers to sing a medley of her biggest hits.

The Let's Get Loud star wore a short white mini-dress and put rumors to rest she was expecting a baby with her slender appearance and impressive dance moves.
