FORMER OC star Rachel Bilson showed off her lithe frame in a white, cut-out Preen dress at the New York premiere of her new movie Waiting for Forever last week.

The starlet paired the bustier dress, which featured a unique yellow neon stripe on the back, with a pair of nude Brian Atwood Maniac pumps and a Cecelia clutch.

In a recent interview with OK! magazine, Rachel said she is in no hurry to wed fiancé Hayden Christensen. The couple got engaged in late 2008 after meeting on set of the thriller Jumper the previous year.

“No, no planning,” the 28-year-old said at the premiere, laughing off the fact that she and her beau aren’t concerned about tying the knot.

But she does hint that Gywneth Paltrow’s mum might be on the guest list, as Blythe Danner plays her mum in the new movie.

“She’s lovely,” said Rachel.
