Gwyneth Paltrow makes her return as substitute Holly Holiday in this week's 'Sexy' episode of 'Glee,' and if this performance of Joan Jett's 'Do You Wanna Touch Me (Oh Yeah)' is meant to set the tone for the episode, it's going to be a wild Tuesday.

A super-sexified Paltrow is joined by Brittany and Santana in this performance of Joan Jett and the Blackhearts' 'Do You Wanna Touch Me (Oh Yeah),' while Will looks on in awe as he pretends to grade papers.

The 'Glee' cast dances around the choir room with sub Holly Holiday, who rocks a full leather ensemble. But still, the ever-modest club coach suggests that her performance is a bit "too much."

Gwyneth gives 'Glee' fans a primetime peep show in this one from the 'Sexy' episode, which airs tomorrow at 8ET on FOX. Season 2, Episode 15 also boasts the much-talked about performance of Prince's 'Kiss' by Ms. Holiday and Mr. Schuester -- which we assume will result in a lip-locking scene!
