Ashley Greene channels old-Hollywood in backless gown as she sparkles at The Apparition premiere She is more usually spotted lounging around in tiny shorts and torn shirts. But when it comes to the red carpet Ashley Green pulls out all the stops. The star channeled old Hollywood in a bright pink backless gown tonight, at the premiere of her new movie The Apparition. Twilight's biggest star? Ashley Greene is a picture of old Hollywood glamour as she poses on the red carpet at a screening of her new movie Apparition in Hollywood In perfect shape: Ashley looks at ease in the spotlight, with her dress highlighting her perfect figure And Ashley looked very inch the movie star, with her brown hair tumbling down her back, a large blue cocktail ring on her finger. The horror flick which also stars Harry Potter‘s Tom Felton is set to hit the big screen August 24. The movie tells the story of a couple haunted by a supernatural presence that is unleashed following a college experiment. While in Twilight Ashley plays supporting actress to Kristen Stewart, career-wise she is fast overtaking her co-star. From drab to fab: Ashley was house hunting in her normal shorts and shirt combo, left, before getting glammed up for her big night out in Hollywood With Kristen and co-star Robert Pattinson currently dealing with the fallout from the failed romance, Ashley has seized the opportunity to shine. The 25-year-old has taken the former couple's place at a series of conventions celebrating the hit franchise. The hit franchise's devoted fans were hoping to see at least one of the stars at the gatherings to celebrate the end of the hit vampire film franchise. But the movie's producers announced neither Kristen nor Pattinson will attend, following the breakdown of their relationship. Ready for their close ups: Juilanna Guill and Alex Lombard arrive for the premiere Ashley is ready to step up to the plate. She told Lucky magazine in March: 'I'm so laser-focused on my career, because when you're dealt these cards you'd be stupid not to.' 'What's most attractive to me is someone who has the same amount of drive as I do, someone who's equally busy.' With a dating history that boasts Joe Jonas, Chace Crawford, Jared Followill and Broadway's Spider-Man, Reeve Carney, Ashley has certainly tried hard to find that special someone.
