A secretly-filmed video will launch the return tour for Ginger Spice Geri Horner, 46, Sporty Spice Mel C, 44, Baby Spice Emma Bunton, 42, and Scary Spice Mel B, 43.

It is a decade since the world’s biggest girl band toured. And the four will send social media into a meltdown with a mock news bulletin in which they poke fun at their personalities.

The vid ends by confirming the UK summer stadium concerts next year — with tickets on sale at the weekend.

Posh Spice Victoria, 44, does not feature in the footage and will not take part in the reunion, instead focusing on her failing fashion business.

But she will still make millions from the tour as an original member of the 1990s chart-toppers with a significant stake in the group’s image and music rights.

A Spice insider said last night: “Girl power is back.

"This is the biggest music comeback of the decade and tickets are expected to sell like hot cakes when they go on sale at the weekend.”

The vid will debut on newly- created band social media accounts Monday afternoon.

And the four will record an episode of the Jonathan Ross ITV chat show on Wednesday, to be broadcast on Saturday.
