Yesterday's news

True love may not run smoothly on "Masters of Sex," which returns for its third season, but it appears to be chugging along just fine off-screen for cute-couple-of-the-moment Michael Sheen and Sarah Silverman, who returns in a recurring role. Josh Charles, who threw one heck of a tantrum on "The Good Wife," joins the cast. 9 p.m. Sunday, Showtime
