Acting couple Lisa Rinna and Harry Hamlin are set to make hit Broadway musical Chicago a family affair when they join the cast as ROXIE HART and BILLY FLYNN respectively. The Hollywood pair, who have both wowed TV viewers with dance routines on successive series of US reality show Dancing With The Stars, have yet to finalise dates for their joint Broadway run. Chicago will be Rinna's Broadway debut. CLASH OF THE TITANS star Hamlin has appeared in Broadway shows including AWAKE + SING!.
