NEW YORK (AP) — Actress Katharine McPhee has played someone who stars in a Broadway show. Now she's really going to do it herself.

The 33-year-old singer-actress tells The Associated Press that she's stepping into the hit musical "Waitress" in April, marking a Broadway debut for the former cast member of "Smash."

McPhee can be seen in the CBS drama "Scorpion."

The 2006 runner-up to the "American Idol" crown also starred in "Smash," the NBC show that focused on the backstage drama surrounding the creation of a Broadway musical about Marilyn Monroe.

"Waitress," the musical adaptation of the 2007 film with songs by pop star Sara Bareilles, tells the story of Jenna, a waitress and pie maker trapped in a small-town diner and a loveless marriage.
