Gwyneth Paltrow returns to Glee as Holly Holliday in Season 2, Episode 15, "Sexy." The stunning star made her first guest appearance in "The Substitute," when she took over Will's Spanish class and New Directions while he was out with one serious fever. ('Memba the mini glee kids?) We'll never forget Holly's catchy rendition of "Forget You" — and now she's back as McKinley's new sex ed teacher, which explains the following salacious performance.

Enjoy this clip of Holly's cover of Gary Glitter's "Do You Wanna Touch Me." We don't agree with Mr. Schue — it's not "too much"; it's amazing.

Even better? Gwynie wraps things up with: "Just remember: When you're having sex with someone, you're having sex with everyone they've ever had sex with. And everybody's got a random." Ahem, Brittany.
