Ricky Martin is sexy ... and he knows it!
The 40-year-old singer will guest star on "Glee" next week as a Spanish teacher who introduces himself to the kids of McKinley High with a Spanglish version of LMFAO's hit "Sexy And I Know It."
"It's one of my my favorite moments in my career," Martin says of the performance, which unfortunately doesn't involve him dancing in a Speedo or Afro.
It sounds like the cast enjoyed themselves as well.
"In my 3 years of 'Glee' I have never seen a guest star walk onto set and literally, everyone is just melting," Chris Colfer adds.
