Let's Talk About Sex! Gwyneth Paltrow to Dish Out Love Advice to John Stamos on Glee

Looks like Gwyneth Paltrow may engage in a bit of dirty talk with fellow Glee guest star John Stamos when the duo returns to the show later this season. As substitute teacher Holly Holiday, Paltrow will briefly take over McKinley High's sex education class and her carnal knowledge may extend itself outside the classroom, show star Matthew Morrison told EW.com.

The upcoming episode will find guidance counselor Emma Pilsbury (Jayma Mays) and her new husband Carl (Stamos) lacking chemistry in the bedroom. "Holly ends up counseling them a little bit,"  Morrison said. “It turns out their sex life isn’t all that. At the same time, I find out the glee club is having a lot of sex and they’re not really informed as to what’s going on. Holly and I come up with an idea to teach them through song about the dangers of sex.”

Morrison also notes that even more sparks will fly between Holly and Mr. Schuester, who. "By the end of the episode, we kind of get together," he said. "She has to leave again, but there’s a possibility of a future between Will and Holly."
