Sir Elton John has cancelled upcoming show in Las Vegas after falling ill with a serious respiratory infection.

The Circle of Life singer checked into Cedars-Sinai Medical Center last night, and was forced to undergo a series of tests.

Speaking to TMZ Elton said: "It feels strange not to be able to perform these Million Dollar Piano concerts at the Colosseum... I love performing the show and I will be thrilled when we return to the Colosseum in October to complete the 11 concerts.

"All I can say to the fans is, 'Sorry I can't be with you.'"

The website reports Sir Elton has since been released from the hospital.
