Glee got a whole lot hotter this week when Ricky Martin arrived on set to film his upcoming episode. As previously reported, the Evita star will appear as McKinley High’s substitute Spanish teacher in an episode slated to air in late January. Glee star Lea Michele tweeted photos of Martin on the show's set on January 5. Check out Martin above with the New Directions crew (Naya Rivera, Mark Salling, Vanessa Lengies, Matthew Morrison, Cory Monteith, Lea Michele, Chris Colfer, Harry Shum Jr., Kevin McHale and Damian McGinty). Michele also snapped a solo photo of herself reuniting with Martin: the two actors appeared together in the Broadway company of Les Miserables in 1996. Don't miss Martin on Glee later this month, and be sure to catch him in Evita at the Marquis Theatre beginning March 12
