Yep, it seems like the world's worst kept secret is out of the bag after Posh tweeted a picture of a (suitably blinging) microphone along with the caption, "Look what I found!! X vb".

Reports suggest Emma Bunton, Geri Halliwell, Mel B, Mel C and Victoria are currently all in London rehearsing for the gig.

The Sunday Mirror's showbiz columnist Dean Piper appeared to back these rumours up when he tweeted: "So the Spice Girls are all together rehearsing for the Olympics RIGHT NOW in London.#itsonbitches.

"Pretty bloody exciting! #spicegirls. I'd like a Spice medley!!! No idea what they're singing..." he added.

It had been previously rumoured Posh was not happy about having to reunite with the rest of the girls for the gig, believing she was "emotionally blackmailed" into performing at the ceremony on Sunday 12 August.

A source told Closer magazine: "Victoria's not happy about it. She thinks it could make a mockery of everything she's worked so hard to do. She's been saying: 'I can't sing and I can't dance anymore.' She doesn't want or need to be known as a Spice Girl now.

"She says she feels 'emotionally blackmailed'. She can't back out without causing a fuss, which she knows will make her look bad, so she feels like she has to do it," they added.

Well, if her Twitter pics are anything to go by, it seems like she's pretty excited about it to us.
