Watch: Jennifer Lopez Gets Wild in London

Jennifer Lopez was all over London this weekend -- in baggy LOVE sweatpants, in head-to-toe snakeskin for the Capital Radio Summertime Ball, and she wore a lot of cleavage and some really crazy hair for her performance on the season finale of the UK version of So You Think You Can Dance last night! 

The songstress arrived for her TV show gig in a bra-baring top and long, wild waves Saturday night then took the stage in a rhinestone-encrusted bodysuit. She came out and belted out her latest hit "On the Floor" while literally getting on the floor with some impressive dance moves. She may be 41, but weknow she can dance.
