Jennifer Lopez performed in NYC on Sunday during the Gay Pride Parade and party.

Jennifer Lopez thrilled crowds at last weekend's (24-25Jun) 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 rumours to rest she was expecting a baby with her slender appearance and impressive dance moves. (source:contactmusic)
