Before Lizzy Caplan booked 'Masters of Sex' as pioneer Virginia Johnson, the actress was best known for her comedic roles in films like 'Mean Girls' and 'Bachelorette.'

The premiere date for Season 2 of Showtime's drama 'Masters of Sex' is getting closer and a new trailer was just released to whet fans appetites.

'Masters of Sex' returns on July 13, but if you're a member of star Lizzy Caplan's family, you probably wont be watching the hit program. Caplan recently confessed that she would definitely be naked for Season 2 and she wasn't letting certain family members watch.

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