Former American Idol Judge Kara DioGuardi's Broadway debut is just around the corner! As she readies to take on Chicago's Roxie Hart beginning September 7, DioGuardi suited up in the merry murderess' signature black dress for a special photo shoot to promote her run in the Tony-winning revival. Access Hollywood stopped by the shoot to chat with the songwriter about her decision to come to the Great White Way as well as her experience penning songs for Chicago veteran Ashlee Simpson and whether Idol co-judges Randy Jackson and Simon Cowell have the chops for Broadway. She even offers up a preview of her rendition of "Funny Honey." Take a look below and be sure to catch DioGuardi this fall at the Ambassador Theatre.
