Jennifer Lopezwas all over London this weekend -- inbaggy LOVE sweatpants, inhead-to-toe snakeskinfor 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 ofSo You Think You Can Dancelast 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 weknowshe can dance.
