Expect things to get pretty hot when Gwyneth Paltrow returns to Glee in March.

"All the kids are lost in their sexual knowledge," says Heather Morris, which means that Gwyneth is there to guide them. That’s right: She’s the new sex-ed teacher!

"She shows us how to put condoms on bananas," says Jenna Ushkowitz. Adds Harry Shum Jr., "I get a zucchini."

According to TV Guide, Paltrow encourages Santana to open up her bisexual side, while at the same time trying to push Sam out of his shell. "Sam's a conservative guy," says Chord Overstreet. "But now he's oddly turned on by Santana's forcefulness."

All this free sexual advice doesn’t sit well with Emma. Neither does the fact that Gwynnie’s character Holly plants a kiss on Will. "I am very, very excited about our kiss," says Matthew Morrison. "Gwyneth calls it her 'freebie work kiss.' That's how she gets to explain it to her husband."
