Lawless, 45, will reportedly play "Mama" Morton in the three night production of the musical.
The actress will star alongside Stephen Moyer of "True Blood" fame, who will play Billy, and funnyman Drew Carey who will star as Amos.
"Chicago," a play about two women who are imprisoned in a jail run by "Mama," is the third longest-running show on Broadway. The play even inspired an Academy Award-winning film starring Renee Zellweger, Catherine Zeta-Jones, Richard Gere and Queen Latifah.
The latest production of the musical -- which will run from July 26 through the 28 -- will be directed by Brooke Shields, who has previously starred in the show on Broadway and in London's West End.
“I could not believe that they had cast Lucy from New Zealand in this iconic musical, a classical American artform, on a hallowed stage like the Hollywood Bowl and they let me [be involved],” Lawless told Fairfax New Zealand News."
The actress will travel to America this week to begin preparing for the show.
“I didn’t dare hope it would happen, and it bloody did. I am beyond excited. Rob Fisher is the original music director and the whole LA Philharmonic will be there, and some incredible stars … an all-star cast … and me.”
