Masters of Sex is adding to its cast again. The newest addition to the Showtime drama is actress Artemis Pebdani. So, who will the It's Always Sunny in Philadelphia star be playing?

More Masters of Sex Season 2 Secrets

Pebdani will be a recurring guest star as Virginia's (Lizzy Caplan) new boss. According to The Hollywood Reporter, Pebdani will be appearing as of now in a few episodes.

Masters of Sex is certainly adding more characters to its show. Erin Cummings was just cast as a prostitute named Kitty. Kitty has a no-nonsense attitude, is smart and calculating, but also "care-taking." She is also an important part of Virginia and Bill's (Michael Sheen) research.

Sexual Revolution Explored Between Bill And Virginia

Sarah Silverman (Sheen's real life girlfriend) and actor Courtney Vance have also been cast in recurring roles.

The drama is sure to start off with a bang as it reportedly picks up with Bill confessing his love for Virginia and the two of them embarking on a real affair. Although the show is obviously about sex, it's also about the connection between Bill and Virginia.

"So much of Bill and Virginia's relationship is never spoken about directly," Caplan said recently. "It's all done with how they look at each other or what they don't say. So, when we show up for work every day, Michael always has very clear ideas about what Bill's thinking, and I always have very clear ideas about what Virginia's thinking."

Masters of Sex starts July 13 on Showtime.
