Inventor Of Pap Smear To Give Bill Masters Competition?  

Silverman is wearing an archaic coiffure -- with a small quiffed fringe in front -- apt to the period drama. The comedienne is peering from behind Yorke's disastrous shock-therapy hairdo, and both of them are working crazy women expressions. While the picture is hilarious, tha kind of humor is deinfitely not going to make it on the show.

"So I met @SarahKSilverman today. Yes, she rules and she's KILLING it on @SHO_Masters. x" York captioned the pic.

Bill Confesses His Love To Virginia In New Preview VIDEO For Season 2?  

Showtime announced that Sarah Silverman will be joining the cast of Masters of Sex for a recurring role in season 2 on April 28.

While nothing else has been revealed about Silverman's character on the show, we do know that she will be called Helen. As a comedienne, Silverman has been damningly honest about sex, to the extent of being a bit obnoxious. So when a personality like that joins the show, she might be donning a sensual role. Enstars wonders if there is a void to fill on the show which Silverman might be stepping in to fill.

Masters of Sex Cast Disses Game Of Thrones Sex Scenes? 

The first promo of the show revealed that Virginia (Lizzy Caplan) will be sick of the oversexualised image that her sex experiments with Bill Masters has wrought. The highlight of the Masters of Sex clip is Virginia (Lizzy Caplan) wanting to pull out from the research experiments with Bill Masters (Michael Sheen). She is seen complaining about being "propositioned for sex a dozen times a day" since the duo's presentation was released in the medical community. In one bit we see her fighting off a colleague in the rest room. She seems to be telling Masters that she is quitting when she says, "I am afraid I have lost my appetite for that."

Could Helen be pitching in on the sex experiments now that Virginia hasn't volunteered?

Season 2 of Masters of Sex returns to Showtime on July 13.
