Rumours of a Spice Girls reunion tour to commemorate the group's 20th anniversary are swirling again.

Mel B, aka Scary Spice, recently said it would be "rude not to celebrate" the anniversary of their chart-topping debut single "Wannabe", adding "hopefully something will be happening pretty soon".

Now US Weekly claims to have been tipped off by a Spice Girls insider, who reportedly said: "This has been in the works for the past year. The girls have long been keen to do a major reunion tour together."

However, fans of Victoria Beckham, aka Posh Spice, and her signature stage move - basically, a sassy point of the finger - could be disappointed, as the source added: "They are trying to convince Victoria to jump in, but she doesn't want to do it."

The Spice Girls last reunited for a short performance at the closing ceremony of the London 2012 Olympic Games. Their 2007-8 reunion tour "The Return of the Spice Girls" included a 17-night run of shows at London's O2 Arena.
