Glee Exclusive: Gwyneth Paltrow, Matthew Morrison to Cover Prince
When Gwyneth Paltrow returns to Glee on March 8, the show will be giving her the royal treatment a Prince song to sing!
In the episode, the Oscar winner will team with leading man Matthew Morrison on a sexed-up version of the onetime glyphs 80s smash, Kiss. The duet represents a huge get for the Fox smashs behind-the-scenes team, as His Highness very rarely licenses his music for television.
Storywise, Paltrows roving substitute, Holly Holiday, returns to McKinley High to fill in for the MIA sex ed teacher. Cue more flying sparks between her and Morrisons Mr. Schuester, and presto, a purportedly too-hot-for-TV version of Princes classic is born. And what would a cover of Kiss be without a literal liplock? Rhetorical question, people. Yes, Holly and Will pucker up.
