The Spice Girls are reuniting for a one-off concert in Hyde Park next year, according to reports.
Emma Bunton, Geri Horner and Melanie Brown have allegedly agreed to a show at the London landmark in July 2017 to mark the 21st anniversary of their debut single Wannabe.
Victoria Beckham has previously ruled herself out of a reunion, while Melanie Chisholm has said she is currently focusing on her solo album.
A source told The Sun: "Mel B, Emma and Geri agreed Hyde Park would be the ultimate way to launch a reunion next July for their 21st anniversary.
"It gives them a year to plan everything and make sure their comeback is spectacular. It would be the most-talked about gig of the year."
According to the paper, Geri is the "driving force" behind the reunion and hosted the planning session at her London home.
Joyce Smyth, who recently brought The Rolling Stones to Cuba for their historic gigs there, is expected to be the band's manager.
The Spice Girls will celebrate their 20th anniversary on Friday.
Wannabe became one of the band's biggest hits, spending seven weeks at the top of the UK charts and earning them a Brit award for best single.
The group unofficially broke up in December 2000 for each to concentrate on solo careers.
They reunited for a series of worldwide concerts in 2008 and at the closing ceremony of the London 2012 Olympics.
