Katharine McPhee Promotes 'Smash' in 'The Voice'

American singer Katharine Hope McPhee, who finished as runner-up in American Idol Season 5, made an appearance at NBC's The Voice to promote her upcoming new musical drama Smash.

McPhee talked about NBC’s new show where she will appear alongside FlashForward star Jack Davenport and Will & Grace’s Debra Messing.

McPhee also said she would be performing her own version of one of Coach’s several hits. McPhee said she would also be performing her own version of Christina Aguilera's Beautiful on the new show, according to the Hollywood Reporter.

Smash, which is a musical drama, revolves around a group of characters who come together to put on a Broadway musical based on the life of Marilyn Monroe. But before that can happen, the people who will try to bring it all together must deal with their own personal acts.

The series will feature original music by composers Marc Shaiman and Scott Wittman. NBC opted to hold the show for mid-season in order to pair it up with the hit reality show The Voice on Monday nights, according to New York Times.

Smash is an upcoming American National Broadcasting Company (NBC) series set to premiere in the 2011/2012 mid-season. Smash stars Debra Messing (Will & Grace), McPhee (American Idol) and Oscar winner Anjelica Huston (Prizzi's Honor).

Smash was written and created by Theresa Rebeck and developed by Robert Greenblatt. Executive producers of Smash are Steven Spielberg and Craig Zadan & Neil Meron (producers of Chicago and Hairspray), and songwriters are Marc Shaiman and Scott Wittman (Hairspray).

The show is a production of Universal Media Studios in association with Dreamworks. The pilot was said to have cost $7.5 million to produce, according to the Hollywood Reporter.
