Ricky Martin - the Latin man with the shaking hips - will be making a guest appearance on Glee in the upcoming February 7 episode.  When Mr. Schue decides to do a Spanish-style assignment for the week, he decides to call on the new Spanish teacher for some help.  Fortunately, the new Spanish teacher just happens to be a very coordinated dancer and singer.  As Ricky describes, "This is how I meet the glee club: 'Hello, nice to meet you.  I'm sexy and I know it.  Let's dance'."

Indeed, Ricky Martin. Even Mr. Schue gets into the act, donning a matador outfit to sing a Latin song.  Here's a preliminary song list for the episode:

-"Sexy and I Know It" (LMFAO)
-"La Isla Bonita" (Madonna)
-"A Little Less Conversation" (Elvis Presley)
-"Bamboleo" / "Hero" (Gipsy Kings / Enrique Iglesias)
-"Don't Wanna Lose You" (Gloria Estefan)

In anticipation of the episode, Fox has put together a little preview video, showcasing some of the performances by Ricky and the glee club, as well as some behind the scenes interviews with the cast.  Chris Colfer notes that "In my three years of Glee, I have never seen a guest star walk on set and, literally, everyone is just melting".

Watch a preview below for the February 7 episode of Glee, beginning at 8:00 p.m. EST on Fox.  You can also watch a trailer and browse through photos for the episode here.
