Photos of Kellan Lutz, Nikki Reed, Pregnant Camila Alves, Paris Hilton, AnnaLynne McCord, Rachel Bilson at Express Party

Kellan, Rachel, and the Hilton Sisters Ask Us to TXT L8TER

Paris and Nicky Hilton slipped into their minidresses and went to the star-studded Express TXT L8TER party at Nobu in LA last night. The event, which was campaigning for people to stop texting while driving, brought out pregnant Camila Alves, who chatted with Rachel Bilson, Mandy Moore, and Ciara. Kellan Lutz happily posed with Nikki Reed amid news that their Twilight costar Rachelle Lefevre has been replaced, something she's not too happy about despite Summit Entertainment's reasoning. Kellan's on-again/off-again girlfriend AnnaLynne McCord avoided the cameras but was spotted leaving the festivities with a friend afterward.
