Hathaway hath regrets.

An underwear-less Anne Hathaway endured every starlet's worst nightmare at the Monday Dec. 10 NYC premiere of Les Miserables -- accidentally flashing her private parts to photographers as she climbed out of a limo, clad in a black taffeta, cape-back Tom Ford dress with a thigh-high slit and bondage style boots.

The recently wed actress unloaded about the mortifying moment the next day at a Tuesday lunch at the Four Seasons, according to the Daily News.

"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," Hathaway reportedly told Vanity Fair writer Ingrid Sischy.

Her unsurprising reaction to the photos, which stormed the web Tuesday morning? "It was devastating," she said. "They saw everything. I might as well have lifted up my skirt for them."

Still, with a brand-new husband, Adam Shulman, and major Oscar buzz building for her portrayal of doomed (and super-skinny!) prostitute Fantine in the musical epic, the star has plenty to be cheerful about.

Shulman stayed by his wife's side at the Monday afterparty for the big premiere at MOMA -- holding hands and swapping adoring glances as they held court at a special table in the VIP area.

"They are loving married life," a source tells Us.
