Ricky Martin is set to guest star on next week's episode of Glee.

In the episode, titled The Spanish Teacher, Will Schuester (played by Matthew Morrison) introduces McKinley High to David Martinez (Martin), whom he meets when he takes a Spanish refresher course. Martinez goes on to become a potential rival for Schuester's position.

In a promo for the episode, a male announcer is heard saying, “Out with the old Spanish teacher, in with guess who? Ricky Martin,” as Martin is seen rehearsing with members of New Directions. (The video is embedded in the right panel of this page. Visit our video library for more videos.)

Martin signaled he was headed to Glee in November when he tweeted: “I hear McKinley high has an opening for a Spanish teacher … Maybe I'll apply. ;o).”

The Livin' La Vida Loca singer is expected to perform a cover of LMFAO's Sexy and I Know It on the episode.

The 40-year-old Martin continues to deny persistent rumors that he's preparing to marry boyfriend Carlos Gonzalez.

However, he did leave the door open to the possibility in remarks to Latina magazine: “We are not talking about it, we're not thinking about it. But I'm so happy that in Europe we have the option. It's amazing to think that we can say, 'I feel like it. I'm ready. Let's go.'”
