(Cover) - EN Star Style - Keira Knightley says she is a Chanel Superwoman in her upcoming commercial for the brand.

The stunning British actress was named the face of Chanels Coco Mademoiselle fragrance in 2006. For the scents latest campaign, she is starring in a short film, shot by Joe Wright the man behind Keiras 2007 film Atonement which is titled Coco Mademoiselle.

The 25-year-old said she didnt quite know what to expect from the advertisement, but when she was told she would be donning a beige catsuit, she was intrigued.

Nobody said exactly what it was going to be like. I knew it was something about a motorbike and I knew it was going to be beige, and they said sort of catsuit and I went OK! she said in a behind-the-scenes teaser. It was completely unexpected. Its a Chanel Superwoman I think.

The commercial for the Chanel fragrance will appear in 30 and 60-second national TV spots, and a corresponding print advertising campaign, shot by iconic photographer Mario Testino, will appear in April issues of fashion magazines.

The mini film is set to premiere on Monday March 21. (C) Cover Media
