Zoe Saldana definitely had something to celebrate at The World of Calvin Klein event in Germany on Wednesday night, where she walked the red carpet alongside Kellan Lutz, AnnaLynne McCord and Diane Kruger.  The swanky soiree, which was part of the Berlin Mercedes Benz Fashion Week, signified the Avatar beauties first event as the new face of Calvin Klein Underwear and Calvin Klein Envy.  The big announcement, which coincided with the fashion week bash marks the first major fashion campaign for the impossibly gorgeous star.  Congrats Zoe!

AnnaLynne McCord may not have a Calvin Klein underwear contract, but the 90210 star, who rocked a figure-flattering blue frock, has the next best thing:  A hunky Calvin Klein Underwear model beau! AnnaLynne kept her The Twilight Saga: Eclipse boyfriend company as he posed for pics on the red carpet, looking devastatingly dapper in a black suit.
