Paltrow's take on the tune will be titled "Forget You." Although it is unclear to whom she will be singing, "Glee" co-creator Ryan Murphy confirmed to E! that she will be part of a "quadrangle" with Emma (Jayma Mays) and Emma's new dentist boyfriend, Carl (John Stamos) and her other suitor, Will (Matthew Morrison).

Murphy said, "Even though Emma [Jayma] is with John Stamos' character, when [Gwyneth's character] sees those two it makes her feel jealous. And that sort of launches another big, wrenching love triangle. Gwyneth will come between them, so it's a quadrangle."

Paltrow, who won her Academy Award for "Shakespeare in Love," appeared in Proof in London's West End and on screen. Her many film credits include, most recently, the "Iron Man" franchise. Her cover of "Forget You" will appear on the upcoming fourth compilation album of "Glee" music.

The first episode of "Glee" to feature Paltrow, "The Substitute," will air Nov. 16 at 8 PM ET on Fox.
