"The way it unfolds isn't typical," Pompeo says of the upcoming episode.

Grey's Anatomy star Ellen Pompeo opened up about the ABC series' upcoming musical episode in an interview with Ellen DeGeneres.

"I don't want to give too much away but the way it unfolds isn't typical," Pompeo said in an interview set to air Tuesday on The Ellen DeGeneres Show. "There is some singing and dancing but basically we're taking songs that the show has made famous like the Fray [the band behind 'How to Save a Life'] and 'Chasing Cars' and those kind of songs and we're singing them. So it's the music you're used to hearing."

The musical episode, which airs March 31, is centered on a character in a coma who is dreaming about the hospital staff singing.

Sara Ramirez's character, Callie, also plays a big role.

Ramirez "won a Tony for Spamalot so she can really sing, so she does the bulk of the singing," Pompeo said.

Pompeo admitted that she wasn't initially excited about the idea of a musical episode.

"When [showrunner] Shonda [Rimes] presented the idea, of course I did my eye roll and the 'Oh, brother' that comes along with it," Pompeo said. "And then we read it and I have to say, I think people are going to love it."

Pompeo added that "they made me" sing.

"I didn't have a choice," she said.
