George Michael has confirmed rumours he will appear in the London Olympics closing ceremony on Sunday, suggesting it had been a poorly-kept secret.

Few details of the closing ceremony have so far been revealed. The singer becomes the most high-profile gay figure in the ceremonies so far.

During Danny Boyle’s opening ceremony, a lesbian kiss from the soap opera Brookside featured during a montage for roughly half a second.

He tweeted today: “Spending most of the next week rehearsing like crazy for the Olympic closing ceremony.

“Obviously a bit nervous not having played for nearly a year, but rehearsals sounding great so far!

“Oh, and , secret? It’s been all over the press for weeks, and I think you all needed to be put out of your misery!”

The Spice Girls are expected to reform for the ceremony while bands One Direction and Muse are due to play alongside. The Who and Take That are also reportedly set to take part.

Blur, New Order, The Specials and the Bombay Bicycle Club are to play at a concert in Hyde Park.
