Anjelica Huston, who plays Marilyn producer Eileen on Smash, teased her singing debut and revealed some season finale details in an interview with ET Online.

ETonline: The season finale features a full staging of The Marilyn Musical — how excited should fans be?
Huston: Oh, very. The dancers are so great. And getting to watch Katharine McPhee and Megan Hilty do what they do so well has been a delight. It’s really something. I get a bit jealous [laughs] and then I see how tired they are.
ETonline: So no songs for Eileen then?
Huston: Well, we have a big full cast musical number coming up that I get to sing in, so that’s fun. I look forward to more next season, that’s for sure.

Check out the rest of the interview, including her take on “a little snake in the grass” called Ellis, on ET Online.

Smash airs Mondays at 10 p.m. EST on NBC. Are you excited for the full cast musical number?
