The Spice Girls are reportedly planning a comeback for the closing ceremony of the Olympics.

Apparently, Victoria Beckham, Geri Halliwell, Emma Bunton, Melanie Brown, and Melanie Chisholm are "95 per cent" confirmed to perform at the closing event.

The group has not sung together since 2008, but could join George Michael, The Who, Take That, Emeli Sande, and Jessie J on August 12.

They have provisionally agreed to sing their 1996 track Wannabe as one of two songs.

Geri is expected to wear a Union Flag dress like she did at the 1997 Brit Awards.

Victoria revealed in a radio interview last week that she would like to appear with the group next month.

"I'm so respectful of my past and I love the other girls. We have some fantastic fans. Who knows, maybe some day we'll do something else with the Spice Girls. I would love nothing more. I don't know about a comeback tour, but I loved being back with the girls. There was a lot of fun. We did so much together and we'll see. If they're up for something, then I certainly am."
