Actress Rachel Bilson is used to looking her best for her glamorous film and TV roles, but it seems she's planning to sport a rather different look with her Halloween fancy dress this year.

The star of The OC and Jumper recently told InStyle magazine that this October 31st she will be dressing as her "ultimate hero", the porcine Muppet diva Miss Piggy.

Bilson, who was recently glimpsed looking highly fashionable at Roberto Cavalli's spring fashion show in Milan, said she is already gathering elements for what she hopes will be a knockout costume, including the "perfect wig and snout".

The star added that she wants to ensure her Miss Piggy fancy dress can do justice to the famously glamorous Muppet, who Bilson says she has "loved practically my whole life".

"I only hope I can look as fabulous," added the actress.

No word on whether Rachel will have a date on Halloween - or whether he'll be dressed as Kermit...
