Ricky Martin and the ‘Glee‘ cast are sexy … And they know it.

Martin’s guest spot as Spanish teacher David Martinez on ‘Glee’ airs tonight (Feb. 7) on FOX and there’s one guiding principle: Martin and the ‘Glee’ cast are having a whole lot of fun with their musical number. Martin leads the singers in a bilingual rendition of the LMFAO synth pop hit. He also incorporates chairs into his sizzling dance routine, too. Only Ricky Martin can make cavorting on a chair look that effortless and so seamless. He’s not the first pop to star to use a chair as a prop, but he makes it look goooood!

The entire cast gets into the whole wiggle thing during the number and the students seem incredibly invigorated by his character’s presence. Hey, if Ricky Martin guest-starred as our teacher, we’d be psyched and wiggle it, too!

The energy in this musical number is so infectious we took a minute to stand up and wiggle it with Martin and co. We bet you did, too.

Tune in tonight to see Martin’s ‘Glee’ debut. It’s “must see” TV.
