Billed to host a Halloween bash at the Las Vegas Venetian Hotel's TAO and LAVO nightclubs later this month, Ashley Greene admits she has found a costume for the affair. To Vanity Fair she opens up, "I can't tell you what it is yet ... O.K., I'm going to be a bird!"

"My stylist found this costume for me because I asked her if I could have it created, and she found this amazing, beautiful costume," she reveals. "I think I'm going to add some feathers to it to make it a little less 'Halloween Sexy Bird.' It's going to be really fun."

Ashley will host the reported Halloween party alongside her "Twilight" co-star Kellan Lutz. They will be joined for the bash, which is planed for Saturday, October 31, by the likes of Rutina Wesley and Sam Trammell of hit TV series "True Blood".

Ashley Greene embraces her fame after starring in "Twilight", thanks to her character Alice Cullen. She will reprise the role in the film's upcoming sequels "The Twilight Saga's New Moon" and "The Twilight Saga's Eclipse".

In further interview with Vanity Fair, Ashley addresses such matters as, how her life has changed since "Twilight" became a hit, her favorite scene to shoot, and her feelings working with different directors on the same character.
