Ricky Martin on : First Look

Say "gracias" to Ryan Murphy and anyone on the Glee team involved with the inspired decision to have superstar Ricky Martin guest star as a musically-inclined night school teacher in the Fox hit.

In the episode titled "The Spanish Teacher," which airs February 7, Will (Matthew Morrison) gives the glee club a Spanish-singing assignment, and enlists the help of a teacher, played by Martin. The talented Latin heartthrob, who will soon headline a Broadway revival of Evita, is expected to perform a sizzling rendition of LMFAO's "I'm Sexy and I Know It," as well as another song.
