Arena returned to the London stage in April 2007, starring as Roxie Hart in the West End production of "Chicago", at the Cambridge Theatre, West End of London. "The Sydney Morning Herald" reported that, "Arena is returning to the stage following the birth of her first baby, Gabriel, now aged 13 months. Arena will make her debut at the prestigious Cambridge Theatre in Covent Garden in April playing the infamous murderess who exploits the media to escape prosecution. Arena said she was "excited, if not a little daunted" about playing the role, which means Arena will have to dust off her dancing shoes for toe-tappers such as "Razzle Dazzle" and "All That Jazz"."
