(Los Angeles, CA) — Elton John has been released from Cedars-Sinai Hospital following treatment for a “serious respiratory infection”.

The 65-year-old singer was treated by doctors and told to rest for seven days.

Sir Elton has cancelled four shows this weekend as part of his Million Dollar Piano residency at Caesars Palace.

Speaking to TMZ, the singer 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.”
