Jennifer Lopez hasn't had a night off from glitz while promoting The Back-up Plan, and again she was at her sparkling best in a gorgeous Georges Chakra dress with metallic heels from the designer too.She practically invented the phrase "That's Hot" so it's only fitting Paris Hilton would be at the Hot Hollywood party.

Attending with Nicky Hilton, both wore sexy mini dresses. Paris's was a Rebecca Minkoff design which she paired with her black Gretchen "Actress" clutch and YSL platforms.

And Nicky wore her strapless lbd with Christian Louboutin pumps.
