London - Hey, George Michael fans: You gotta have faith.
The former Wham! star has confirmed he will be performing at the Olympics closer on Sunday.
He tweeted on Tuesday: "Spending most of the next week rehearsing like crazy for the Olympic closing ceremony."
Michael was hospitalised with life-threatening pneumonia late last year but has since recovered.
He tweeted that he was "a bit nervous not having played for nearly a year," but said rehearsals were sounding great.
Roger Daltrey has confirmed that The Who will play the ceremony, billed as "a symphony of British music."
No confirmation yet on the widely rumored Spice Girls reunion.
