Gwyneth Paltrow To Sing Rihanna's 'Umbrella' On 'Glee'

What a wild mash-up of songs about rain! On Tuesday, CMA performer and Oscar winner Gwyneth Paltrow will make her much-hyped debut on "Glee" in an episode called "The Substitute," and a preview of one of her songs has hit Justjared.com.

Paltrow takes on Rihanna's smash "Umbrella," and Mr. Schuester (Matthew Morrison) appears on the song singing lines from the classic Gene Kelly tune "Singin' in the Rain." The tracks mash up surprisingly well, and not just because of their obvious thematic similarities. Putting a modern, funky edge on the Kelly tune, which appeared in the 1952 film of the same name, updates the track and makes it seem like it could have easily appeared on Rihanna's 2008 hit.

Paltrow will also sing a cleaned-up version of Cee Lo Green's instant classic "F--- You." In a clip that appears on EW.com, Paltrow's character, a substitute teacher filling in for Mr. Schuester, proves her hipness to the kids in New Directions with her sassy rendition of the track, changing the song's lyric to "forget you." Soon the entire Glee club participates in the sing-along, expect for a very unhappy-looking Rachel.

Paltrow will appear in two episodes of the hit Fox show, proudly displaying her mad singing skills. "Gwyneth is a great singer," "Glee" creator Ryan Murphy said. "She's done it a little bit, but I really want to show it off and show everyone how great she is."
