Rachel Stevens has been donning film fancy dress after she landed the job of hosting the 2011 Orange Baftas in London.

The former S Club 7 singer will interview top celebrities and present links to the public as part of the job, which she will undertake on February 13th at the Royal Opera House.

As part of the publicity for Orange Wednesdays, Stevens wore ballerina fancy dress to emulate Natalie Portman in Black Swan, one of the movies tipped for success at the ceremony and at the Oscars.

She said she was thrilled with being given the chance to anchor the Baftas, as well as at being able to dress up as Portman's character.

"Unfortunately the tutu and makeup isn't quite right for the red carpet so I'll be swapping the ballet pumps for heels and a glamorous dress on the night," she joked.

Stevens recently gave birth to her first child, a little girl named Amelie.
