The New Directions go crazy over Ricky Martin, who guest stars on Glee as the sexy, new teacher at McKinley High.  The singer performs a Spanish-English mix of LMFAO‘s “Sexy and I Know It.”  Martin’s episode airs February 7.

Love Ricky’s moves?  You can see him live at the Marquis Theater beginning March 12 when he hits the Broadway stage in Evita.
