'Glee': 'The Spanish Teacher' in pictures

If you need more Glee in your life, well, you're in luck - it's just around the corner! And what's more, you might have heard that this week's episode has a rather special guest. A very special guest. A Ricky Martin-shaped guest!

We can't wait to see what Ricky has to offer the show - he's playing a Spanish teacher who helps Will and the New Directions with a Spanish singing assignment. Fancy!

Of course, there's loads of other stuff happening too - what's going on in Mercedes's love life? And how will she and Kurt respond when Rachel lets slip about Finn's little proposal? We can't wait to find out!

Take a look at some photos from the next episode of Glee, 'The Spanish Teacher', below!

Glee airs on Tuesdays at 8/7c on Fox.
