Rosie Huntington-Whiteley feels ''flattered'' when women flash their underwear at her.

The 27-year-old model - who launched her best-selling lingerie and sleepwear line, Rosie for Autograph, with Marks & Spencer in 2012 - has revealed women often approach her and show her their underwear looking for her seal of approval.

She explained: ''Women come up to me and flash their bra strap or knickers. I'm flattered because it's usually their way of telling me they're wearing my designs or want my advice. I guess I get excited about people flashing me their underwear for totally different reasons than most people would.''

Rosie - who has been dating Hollywood star Jason Statham since 2010 - designed the collection for women to feel ''chic'' but ''comfortable'' at home.

The blonde beauty - who models the collection herself - also insisted her real life is a world away from how she is portrayed in the stylish ad campaigns.

She told the Mail on Sunday newspaper: ''I've collected retro lingerie for years, so my girlfriends are always asking me if I just waft around the house in vintage underwear: Of course not - I'm as real as anyone else. But I spend a lot of time at home when I'm not working and I want to feel good there. I think that's why I was so insistent that the Rosie for Autograph sleep and lingerie collection would be comfortable and cosy - but still make women feel chic.''
