Maybe it was just laundry day for Anne Hathaway?

The actress showed up last night for the NYC premiere of Les Misérables and while she had the high-end fashion, hair and accessories covered, her stylist apparently forgot to mention that underwear goes well with any red carpet look. Unfortunately for Anne, not getting that memo meant she pulled a Paris Hilton and flashed the goods to photographers as she exited her car!

So how did Anne respond? Well, she didn't. Apparently, she wasn't even aware she flashed photographers and went on to pose for (fully clothed) red carpet pics like nothing happened!

Les Misérables, which also stars Russell Crowe, Helena Bonham Carter, Hugh Jackman and Sacha Baron Cohen, hits U.S. theaters on Christmas Day.

What do you think of Anne's underwear-free entrance?
