Together againThe Spice Girls in their heydayThe Spice Girls are planning to reform next year for a 10th anniversary show.

And music industry experts predict the fab five could pick up an astonishing £10m EACH if they went on a world tour.

Mel B let the cat out of the bag on GMTV when she revealed the girls are close to agreeing a deal to team up again.

Their first single Wannabe hit the charts in July 1996 - and they want to celebrate with a special show and the release of a greatest hits CD.

When Mel was asked if they will get back together, she replied: "I think so, but that's just me.

"Hopefully next year, if we can get everything sorted and together."

And she added she has spoken to two of the girls - and will speak to the others shortly.

"Emma and Melanie have been to visit me and I am going to be having dinner with Geri soon," she said.

"I haven't been to see Victoria because I've been working... but everything is cool on that front."

None of the girls have had much success in their solo careers - but together they could earn megabucks.

An insider is quoted as saying in The Sun: "They are considering playing at the new Wembley Stadium next year.

"It would be a dream venue and there's no doubt they would pack it out."
