Kara DioGuardi as Roxie Hart in Chicago

Kara DioGuardi will star in Chicago on Broadway as Roxie Hart. She begins her run on September 5. So excited! I'm going to get tickets. I've never seen Chicago before so this is great.

Access Hollywood has a video of her transforming into Roxie and singing a few tunes from the show.

She's like a real life Katharine McPhee now in Smash.

From Access Hollywood:

Kara, who begins her run on Broadway on September 5, said she has a lot in common with the classic character.

“Feisty. She’s a bit of a survivor. She’ll kind of do whatever it takes to get the job done… That didn’t sound so good, but you know what I mean. She’s quick on her feet, so that’s good,” Kara told Access Hollywood Live’s Billy Bush when asked to compare herself to Roxie.

While she has the pipes, Kara said not every part of Roxie came easily.

“The first day, I told them I’m not really a great dancer,” she laughed.

Kara revealed she actually is wearing the same costume worn by a woman she wrote songs for – Ashlee Simpson, who previously played Roxie on Broadway.
