Let her entertain you! Katharine McPhee is ready to show off the full range of her talent in Smash, a spectacular new TV series about the making of a Broadway musical. The singer/actress stars as Karen Cartwright, a Midwestern girl looking to make it big on the Great White Way. "What I love about the show is that it’s about dreams," says McPhee, who got her first taste of fame as a contestant on Season 5 of American Idol. "And how no dream is too big." Watch the video above for an exclusive look at the singing, the stars—keep your eyes peeled for Debra Messing and Anjelica Huston!—and the backstage drama, and mark your calendars for the premiere of NBC's Smash on Monday, February 6th at 10/9c.
