Big Brother and Neil Morrissey aren't the only entertainments being blamed for the collapse of Les Dennis and Amanda Holden's marriage. The West End production of Chicago reportedly has a part to play, too. Back in 2000, comedian and game-show host Dennis appeared in the musical as Amos Hart, aka "Mr Cellophane", Roxie's cuckolded husband, but he left in order to spend more time with his wife. Apparently not so concerned with spending nights at home, Holden - best known for her TV roles in series such as Cutting It and Hearts and Bones - is said to be poised to join the cast of the musical. Several newspapers have tipped her to take over from Gaby Roslin as prison matron Mama Morton in the spring. A spokesman for Chicago has, however, denied this. He told Whatsonstage.com today that the actress has not even been seen for a role in the show.
