Ricky Martin to guest star on 'ER'

Singing heartthrob Ricky Martin, who used to star in ABC's long-running soap-opera "General Hospital", will be a guest in the ER next year, Rolling Stone reports.

"Believe it or not, I'm a frustrated doctor," Martin said. "And it would be a great place to let my frustration go. I love medicine".

TV audiences seem to be big fans of medicine, too. "ER" has been a top-rated series since its debut in 1994.
