American Idol runner-up Katharine McPhee made an appearance on the competition show The Voice last night to promote her new series, Smash.
Before Christina Aguilera took the stage with Beverly McClellan on The Voice to perform "Beautiful" together, Katharine chatted with Carson Daly about how she'll be performing that same hit song on the upcoming new series, Smash.
The new NBC musical drama will also star Debra Messing and Jack Davenport.
Smash will air before The Voice on Mondays this winter.
