Listen to Kellie Pickler on iHeartRadio

Kellie Pickler says since her run on "Dancing With the Stars," her interest in signing on for a Broadway show has really grown.  

The singer tells "Country Weekly" a musical would give her the chance to combine her two "passions -- dance and music."  She explains that she really wants theater producers to stage at biographical show about Tammy Wynette, because "if anybody lived a country song, it's Tammy." 

Pickler's Broadway aspirations have one problem, though -- there are no Tammy Wynette musicals waiting to be produced. 

But Kellie says there's also an existing show she'd like to take on.  The country star explains that her "Dancing" partner Derek Hough has told her she'd be great in the role of Roxie in the musical "Chicago."  Pickler says she'd love the opportunity to give it a try, especially since she's already done some of the prep work.  She explains that she's seen the film version of the show "a million times" and knows it "by heart."
