We’ll give her some credit — Gwyneth showed off serious Spanish skills when she filled in for Mr. Schuester last season (even if they were used to dish on Lindsay Lohan). But just wait until tonight, when things will heat up as Ricky Martin guest stars as a night school teacher who gives Will some pointers. (Helps to be a native speaker!) Along the way, Martin (as David Martinez), does a hot number with Santana, and the rest of the cast also plays homage throughout the show to Latin pop favorites from Gloria Estefan, Enrique Iglesias, and more.

If you haven’t seen it already (or just need to see it five more hot times), check out the clip of Martin performing LMFAO’s “Sexy and I Know It” from tonight’s episode.

It’s a pretty big episode, Ricky Martin aside, with Rachel debating her future, Blaine recovering from surgery, and the (re)budding romance between Sam and Mercedes.

Come back after the show and tell us if you think Martin was living la Glee-da loca (sorry I had to!) live at 8p.m. Eastern/7 p.m. Central. And check out this post after you’ve watched “The Spanish Teacher” to share your reactions, and look for our full recap tomorrow!

Have you practiced your salsa moves yet this week, PopWatchers?
