Dancing On Ice judge Robin Cousins could be the last Billy Flynn to take to the stage in long-running West End show Chicago.
It has been announced the show is to close on September 1 after nearly 15 years. The Olympic medal-winning skater is joining the cast from 17 July.
The musical, which went on to be made into an Oscar-winning film starring Catherine Zeta Jones, holds the record as the West End's longest-running revival.
Brooke Shields, Christie Brinkley and David Hasselhoff are among the stars who have taken to the stage in guest roles over the years.
Barry Weissler, who has produced the show along with his wife Fran in New York, London and other locations around the world, said: "Bringing Chicago to the West End was a pivotal moment in Fran's and my career. Running 15 years has been a dream come true. We may be taking our parting shots for now, but the Razzle Dazzle will never fade."
The show drew instant acclaim when it opened in November 1997 with Ruthie Henshall, Ute Lemper, Henry Goodman and Nigel Planer in the main roles.
Others who have appeared include Ugly Betty's America Ferrera, Anita Dobson, Jill Halfpenny, Denise Van Outen and Gaby Roslin.
It originally opened at the Adelphi Theatre, later transferring to the Cambridge Theatre and then moving to its present home at the Garrick Theatre last year.
It has taken more than £120 million at the box office in London.
