Just a little booze will do! Lizzy Caplan may strip down like it's no problem in Showtime's Masters of Sex with Michael Sheen, but the 31-year-old actress admits she's previously had to drink to calm her nerves before getting naked for the small screen. During an appearance on Chelsea Lately Tuesday night, the star revealed that she turned to vodka to prep for a sex scene during her guest-starring role on True Blood in 2008.

"I was hammered for that," Caplan told Chelsea Handler about her HBO experience. "I didn't really have lines the first time. It was like 7 a.m. in the morning and I was chugging vodka completely naked while a makeup artist I had just met was on her knees in front of me sponging my ass. It's intimate."

During her six episode stint, Caplan played the role of Amy Burley, a love interest for Jason Stackhouse (Ryan Kwanten). The two had several graphic nude scenes together, until her character's untimely death. But there was one detail during her stay in Bon Temps, Louisiana, that viewers were never aware of.

"On True Blood -- I've never told anybody this -- but I was so nervous and then I was so drunk that after I shot the scene I was going up to the crew members -- I had just met all these people the day before -- and I was going up to all of them like, 'You got a boner! You do! You've got one!' It was horrible," she said, laughing, to Handler. "Horrible!"
