Ricky Martin is thinking about adopting a girl but isn't getting married. All that personal activity hasn't stopped him from getting back to work! The singer tweeted a photo from the set of 'Glee,' where he will play a musically-motivated Spanish teacher on an upcoming episode of the blockbuster series. He will reportedly headline two musical numbers during his stint. So Lea Michele and crew will be 'Livin' La Vida Loca' for a bit!

Martin tweeted: "First day!! :o)" and shared a photo of himself and cast members like Michele, Naya Rivera, Chris Colfer and more.

Martin and Michele have prior work history, starring in a past production of 'Les Miserables' back in 1996. So this is a reunion of sorts for the pair. She tweeted that Martin is "seriously the sweetest and a great fit for our show." Uh, yeah he is!

What a love fest on the set of 'Glee' right now. Just look at those smiles in that photo. We're looking forward to seeing Martin on the show.
