A musical based on the lives of Victoria and David Beckham is in production.
The satirical play, entitled 'MacBecks', is set to open in January.
Long Road Productions, who are involved in the musical and have previously worked with 'Riverdance', say the production draws inspiration from Shakespeare.
The company's director, Ronan Smith, said: "We're very excited by the script - it's a wild comedy romp that borrows from Shakespeare's 'Macbeth', 'King Lear', 'Romeo and Juliet', as well as Cyrano de Bergerac. It will be a musical based on the world's best known soccer player."

Mariah Carey and Nick Cannon's marriage is reportedly on the rocks.
