Gwyneth Paltrow returns as sassy substitute teacher Holly Holiday in next week's 'Sexy' episode of 'Glee' -- and if the title is any indication of what to expect, we think it'll be a steamy one!

Paltrow shines in 'Sexy' as she returns to McKinley High to school the kids -- and glee club coach Will -- with a little sexual education.

Ms. Holiday will rock out some classic hits, like Joan Jett's 'Do You Wanna Touch Me (Oh Yeah) alongside the 'Glee' stars, and get up close and personal with Prince's 'Kiss' to heat things up in her budding romance with Will. Paltrow -- Holiday --  will slow things down a bit with a right-on rendition of Stevie Nicks' 'Landslide.'

Also, rumor has it that big bully football player Karofsky will come to terms with his sexuality -- and feelings for Kurt -- with a performance of Lady Gaga's 'Born This Way.'

'Glee' was absent this week as 'Idol' moves into its final contestants, but will return with Gwyneth Paltrow and 'Sexy' on March 8.

- Holly Holiday and Will, ‘Kiss’ (Prince)
