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!
