Nigel Hall of Cowell's production company Syco Entertainment announced the closure and said: "Alongside Stage Entertainment we'd like to thank the cast and crew who have worked so hard on this show.
"To everyone at Really Useful Theatres and the ever supportive staff at the London Palladium, and everyone involved in I Can't Sing! I'd like to say a huge thanks and the very best of luck with their next venture."
The news of its closure follows a number of other recent high-profile West End casualties. A stage version of hit film The Full Monty closed after five weeks, Andrew Lloyd Webber's musical Stephen Ward lasted for four months and the curtain came down on Sir Tim Rice's From Here to Eternity after six months. The West End is a tough place to be.
