The Jennifer's Body's other sexy star with Megan Fox wore an asymmetrical teal Helmut Land cowl-neck sleeveless dress paired with nude Brian Atwood pumps. Sans jewelry and with light makeup she had styled her blond hair in loose waves framing her face.

Amanda posed for the photogs with co-star Jullianne Moore on the red carpet.

After sharing a lesbian smooch with Megan Fox in Jennifer's Body, Amanda will be seen in another flesh baring role in Chloe, getting steamy with her co-star Julianne Moore. She plays a troubled prostitute alongside Moore and Liam Neeson. Its a story of three people embroiled in a story of love and betrayal.

Amanda, 23, has been dating her UK based Mammaa Mia co-star, Dominic Cooper, 31, whom she met on the film set.

Amanda recently conceded there are plans to make a Mamma Mia sequel, in which she played lead as Sophia. She had earlier denied knowledge of a follow-up but now says, "I've been talking to some insiders and it's not something that they haven't been working on. I don't actually know anything other than that."
