Singer Ricky Martin on Friday tweeted a photo of himself and the cast of the Fox musical-comedy Glee.

“First day!! :o),” Martin tweeted along with the photo to his more than 4.7 million followers.

Glee co-stars Matthew Morrison, Cory Monteith and Lea Michele also tweeted about Martin's guest spot.

“Our new Spanish teacher,” Monteith tweeted along with a photo of himself and Martin.

“What a great guy,” Morrison messaged, “having a lot of fun shooting our scenes together.”

Michele added: “Having so much fun on the set with Ricky! He's seriously the sweetest and such a great fit for our show!”

In a new cover interview with Latina magazine, the Puerto Rican singer for the first time addressed the rumor that he's planning to wed his boyfriend Carlos Gonzalez in New York later this month.

“We are not talking about it, we're not thinking about it,” Martin said. “But I'm so happy that in Europe we have the option. It's amazing to think that we can say, 'I feel like it. I'm ready. Let's go.'”

He added that he's considering adding a baby girl to his family, which includes twin boys Valentino and Matteo.

“I think that I'll do it later on this year, so that [the kids] are not too far apart in ages. A little girl! Dios mio, me muero (My God, I would die) … But we're going to talk about that later on. It would be irresponsible to do it now.”
