The Spice Girls have started recording their new album - well, three of them anyway

The Spice Girls are back in the recording studio.

Geri Horner and Emma Bunton - who make up two of the original five members of the girl group alongside Mel B, Mel C and Victoria Beckham - have taken to Instagram to share an image of the two of them in a studio ahead of the 21st anniversary of their debut single Wannabe.

The photo, posted to Geri's Instagram account, was simply captioned: "In studio,oooooh @emmaleebunton (sic)"

But any new music to come out of the studio sessions won't be branded as Spice Girls music, as Mel C and Victoria are refusing to take part in the reunion, leaving Emma and Geri - who announced she is pregnant last month - to form a trio with Mel B called GEM.

The talk of new music will be good news for Victoria, 42, as she previously admitted she doesn't want the trio to sing Spice Girls material when they go out on their reunion tour.

She said: "Of course, as a new group, I do [wish them luck]. I do think they should sing new material, though, because what we did as the Spice Girls was so special. If they sang Spice Girls songs, I think I might be a bit sad."

The studio visit comes after Geri, 44, Emma, 40, and Mel B, 41, announced back in July that they would be heading out on a reunion tour.

They said in a video: "You've stood by us for 20 years and we want to say a big thank you.

"We've had our ups and downs but you have always been there. We want to celebrate and have a party, and when we do, you're invited."
