Anna, Nikki, and the Hiltons Celebrate J Lo's Style and Us!

Us Weekly gathered its usual suspects last night to celebrate this year's Hot Hollywood issue in LA. Its Icon of the Decade, Jennifer Lopez, had all eyes on her posing with Marc Anthony before heading inside, where the pair let loose with some dirty dancing. Marc has been by Jennifer's side nonstop for the past week in the run-up to The Back-up Plan's release today — check out Buzz's review and enter to win her onscreen accessories. Paris Hilton and Nicky Hilton had a girls' night out, stopping by the bash to party with J Lo after attending an ALS charity bowling event. Nikki Reed and Paris Hilton share an ex in Paris Latsis, but there was no drama as the Twilight star hit the red carpet. Adorable Anna Kendrick, who also made the magazine's list, was on a break from filming in Vancouver. Anna and Nikki have only two months to go before Eclipse hits theaters, and today we got to see the exciting final trailer!
