Anne Hathaway (Reuters file photo) Lambert no fan of 'Les Mis' voices 'Les Miz' beautiful, but is it enough? Hathaway flashes genitals at premiere Jackman gave Seyfried a lap dance

Actress Anne Hathaway was "devastated" when she suffered a wardrobe malfunction and accidentally exposed her genitals at the New York premiere of her latest movie Les Miserables on Monday.

The usually demure star was climbing out of her chauffeur-driven car at the Ziegfeld Theatre when a slash in her figure-hugging black dress revealed she was not wearing underwear.

Hathaway managed to stay calm and appeared completely unfazed by the incident before joining her co-stars Hugh Jackman, Russell Crowe and Amanda Seyfried on the red carpet before the screening.

However, she was later overheard telling Vanity Fair writer Ingrid Sischy that she was mortified by the incident and blames her dress for being so tight, according to the New York Daily News.

She told Sischy, "I was getting out of the car and my dress was so tight that I didn't realize it until I saw all the photographers' flashes. It was devastating. They saw everything. I might as well have lifted up my skirt for them."

Despite her upset, editors at New York Post gossip column Page Six report that Hathaway later laughed off the incident after discovering the explicit photos had gone viral on the Internet, adding, "And I just thought, 'OK, where's the comedy?' It has hit. It has landed. A bomb has gone off. I think what I am going to do is whatever my next appearance is... I'm going to step out of the car in a blanket. You've got to laugh at it."
