Quick, which actor on this cast list is just happy to be here: Daniel Day-Lewis, Nicole Kidman, Penélope Cruz, Kate Hudson, Dame Judi Dench and Fergie?
That's right, thanks to Chicago director Rob Marshall, Fergie will play a prostitute in the movie musical Nine, alongside those Oscar night faves, according to an Associated Press interview.
"I'm speechless," says Fergie, 33, who will sing a duet, "Be Italian," with Day-Lewis.
"[My character] introduces him to the world of sexuality," said the Grammy winner. "It's a very strong song. I'm just thrilled I get to play a character."
That's not all she's psyched about: The "London Bridge" singer can't wait to watch her costars in action when filming begins in October.
"I'm definitely going to be a sponge on set," said Fergie. "I want to pick up on everything that all these brilliant actors are bringing to the table."
She added: "I'm probably going to be the quietest that I've ever been while working just because I want to watch and learn."
But Fergie is no big-screen rookie: She's also appeared in Poseidon and last year's Grindhouse.
And in other Fergalicious news, the singer is currently working a new album with the Black Eyed Peas.
"It's a new sound," she said. "We're not doing the same old thing. We're not trying to copy what's out there on the radio. We're being artistic and pushing the envelope."
