'Glee': Ricky Martin Sings 'Sexy And I Know It' in 'The Spanish Teacher' (VIDEO)

Ricky Martin is sexy and he knows it. The Latin heartthrob is guest-starring as a Spanish teacher in an upcoming episode of "Glee" in February, called "The Spanish Teacher," and Martin is covering another bon-bon shaking hit, LMFAO's hit single, "Sexy And I Know It."

Fox has released the first sneak peek of the episode, featuring Martin singing the pop hit in a mix of both English and Spanish. And yes, he's definitely shaking his bon-bon -- and inspiring some of the New Directions to do the same. Finn (Cory Monteith), what are you doing?

We knew that Martin's character would give Mr. Schue, played by Matthew Morrison, some kind of trouble, but we never anticipated an Español-off.

"I go to night school now because I need to know how to speak Spanish so I can teach Spanish," Morrison dished to Access Hollywood. "He comes in and I bring him into the Glee Club and people like, really love him, he's a great teacher and stuff, so my job is kind of on the line now because the kids really love him."

And it's not just for the cameras! The "Glee" cast also warmed up to the "Livin' La Vida Loca" singer. Lea Michele tweeted a photo of herself with Martin last week, tweeting, "He's seriously the sweetest and such a great fit for our show!"

So how does Mr. Schue plan to win back the New Directions?

"We have to have a kind of Español-off. So he does a song, I do a song," the "Glee" star told Access. "His will be an LMFAO song," said Morrison, confirming the Latin heartthrob performs the band’s current hit single, "Sexy and I Know It." "Mine will be an Elvis Presley song -- in Spanish."

Meanwhile, Morrison isn't the only one tackling songs in Spanish. The boys of the glee club also had to sing a song entirely in Spanish.

"It's the opening of the episode," Kevin McHale told HuffPost TV in a recent interview. "It's completely in Spanish, and it literally was the hardest thing. I don't even know if we did one take where we got all of the words right. Cory [Monteith] was like, 'You do know I'm from Canada, right?'"

"Glee" airs Tuesdays at 8 p.m EST on Fox. Watch Martin cover "Sexy And I Know It" below.
