Mary-Kate and Ashley Olsen's kid sister is most definitely ready for her closeup -- clothing optional!

Classically trained actress Elizabeth Olsen, 22, is getting Oscar buzz for her performance in indie thriller Martha Marcy May Marlene, out this fall. Posing in a bra and blazer in GQ, she says she didn't flinch about one creepy nude scene in the film, in which her body is "offered up" to a man for sex.

"The movie wouldn't have been as disturbing without it," she explains. "Taking away someone's sexuality, making it something you don't even own anymore--that's the scariest thing."

Also scary? Growing up with kid stars Mary-Kate and Ashley, who were besieged by fans and photographers wherever the family went.

"The paparazzi were really frightening," Elizabeth tells GQ. "I thought, Maybe I'll just skip that part."
