In her new Showtime drama Masters of Sex, Lizzy Caplan plays groundbreaking sex researcher Virginia Johnson, so on last night's Watch What Happens Live after show a viewer asked the actress to combine her love of the Real Housewives franchise with her newest gig and name the 'Wife who's the real master of sex.

Caplan, who says she watches all the Housewives series except for Miami (sorry, Mamis!) quickly joked that Lisa Vanderpump "earns that name" before selecting Kim Richards, then swiftly changing her mind once again: "Actually Phaedra [Parks] is the master of sex," she says. "She's my number one, when she talks about putting powdered sugar…" (We know where Caplan was going with that.)

Another viewer wanted to know if Caplan is currently in a relationship. "I am dating somebody right now but I don't ever talk about that stuff or who it is," she admits.

Watch Lizzy Caplan talk love, sex, and Real Housewives and tell us in the comments: which Housewife do you think is the sexiest?
