Amanda Seyfried really loosens up after a few drinks!

The actress appeared on The Late Show With David Letterman Dec. 11 to promote her new movie, Les Miserables. During her interview, however, the 27-year-old admitted to being a bit tipsy.

"I'm pretty drunk. To be honest with you Dave, I've had about three," she deadpanned. "I'm a big fan of whiskey. I had some Midleton. [My costar] Russell Crowe gave me some Midleton for my birthday and I had some of that before I got here. And then your lovely colleagues had some Jameson waiting for me [backstage]."

She added, "I have to go on record saying I've never done a live television show -- after noon -- without some kind of liquid courage."

While Seyfried recognized that she might "have a problem, maybe," the starlet has no intention of staying sober for TV interviews. "You know what? It really gets me through, and I really wanna enjoy my experience out here because it's special."

When the TV host jokingly asked Seyfried is she'll ever end up in rehab, she giggled and replied, "No!"

According to Seyfried -- whose ex-boyfriends include Dominic Cooper, Ryan Phillippe, Alexander Skarsgard and Josh Hartnett -- she's been on a bit of a bender. "I don't drink often. I swear, I don't! I've been with the [Les Miserables] cast a lot. . . and it's really fun because we all really like each other. None of us really drink."

Before the interview ended, Letterman toasted the star with another glass of Jameson -- her fourth -- before signing off.
