'True Blood' Season 5: Valentina Cervi Had Never Seen HBO Series

Valentina Cervi may be an avid fan of her show now, but the "True Blood" star wasn't always a Bon Temps expert.

"I had never seen ['True Blood'], so I watched the first four seasons on a weekend when I got the part, and totally got hooked," the actress, who plays Salome, told "I thought, ‘Oh my God, I’m so lucky to be a part of this.’"

A little background on "True Blood" may have better prepared Cervi for her audition -- or at least the sex scenes. Luckily, Alan Ball put her at ease by telling her not to be afraid to "use her sexual power."

"The writer asked me to be naked on the bed, and I kind of said, 'Oh … ' but she explained to me that Salome is free," Cervi told Vulture in an interview. "She doesn’t cover herself up. I totally got that, and it helped me out in the scene."

"True Blood" was renewed for a sixth season this week. Its most recent episode saw solid ratings with 4.7 million viewers. The show airs airs Sundays at 9 p.m. ET on HBO.
