George Michael will make his stage comeback after his brush with death last year by performing at the closing ceremony of the London Olympics.
Rumors of the star's involvement in the extravaganza have been swirling for weeks, and now he has officially announced the news on Twitter.
When one follower asked if the show was supposed to be a secret, he replied:
It will be the first time Michael has performed live in public since he was hospitalized at the end of last year with a life-threatening bout of pneumonia. The illness forced him to pull the plug on a string of concerts.
The Spice Girls are also expected to reunite for the ceremony - the first time they have performed together since 2007.
The closing ceremony of the London 2012 Olympic Games takes place on August 12.
