Geri Halliwell, Emma Bunton, Mel B and Mel C are reportedly planning another reunion tour, although further details remain unknown.

Ginger, Baby, Scary and Sporty Spice discussed getting back together over dinner at The Palm restaurant in London's exclusive Knightsbridge district on Wednesday night (16.09.09).

Mel B later hinted at an imminent reunion, writing on her Twitter account: "Spice girls, stadiums?????????? Had dinner with the amazing melc emma and geri I love them so much (sic)."

It is understood the foursome continued negotiations at the nearby Mayfair Hotel, where they enjoyed several cocktails.

Fellow bandmate Victoria Beckham was not at the meeting, believed to be because she is busy launching her Spring/Summer 10 collection at New York Fashion Week.

The girl group shot to fame in 1996 with their hit single 'Wannabe'. They sold over 65 million albums before going their separate ways in 2001.

They briefly reformed in 2007 for the hugely successful 'Return of the Spice Girls' tour, which saw them perform 47 concerts across the world.
