Gwyneth Paltrow will do more than just cover "Landslide" when she returns to Glee next week.

As Holly Holiday, the Oscar winner will take over the school's sex education class, eventually focusing on one couple in need of bedroom tips: Emma and Carl.

"It turns out their sex life isn't all that," Matthew Morrison tells Entertainment Weekly, not exactly revealing a bombshell, considering these two barely know each other and, well, Emma is really, really neat.

What other sexual activity will play a role on an episode aptly titled "Sexy?"

"I find out the glee club is having a lot of sex and they’re not really informed as to what’s going on," Morrison adds. "Holly and I come up with an idea to teach them through song about the dangers of sex.”

So, we've had the bullying episode... the alcohol episode... and now we can look forward to the sex episode. Sound off in our Glee forum: are you excited for it?
