The Spice Girls plan reunion concert

The Spice Girls are planning a reunion concert in 2017.

Three members of the girl group – Mel B, Emma Bunton and Geri Horner – are reportedly set to mark the 21st anniversary of their debut album with a huge gig in London’s Hyde Park next July.

A source said: "Mel B, Emma and Geri agreed Hyde Park would be the ultimate way to launch a reunion next July for their 21st anniversary.

"It gives them a year to plan everything and make sure their comeback is spectacular. It would be the most-talked about gig of the year."

The ‘Wannabe’ hitmakers have teamed up with music manager and lawyer Joyce Smyth and PR guru Alan Edwards, who worked with them in the 90s.

It is not yet know whether fellow bandmates Victoria Beckham and Mel C will be joining them but the 42-year-old fashion designer is considering it as she would love for her four-year-old daughter Harper to see her as a part of The Spice Girls.

The insider added to The Sun newspaper: "Victoria likes the idea of Harper seeing her just once as a Spice Girl because she wasn’t born for the reunion in 2008. It’s a long shot but there’s a chance she would join in at the London date."

Meanwhile, Mel B previously revealed the group were forced to push back their 20th anniversary plans.

She said recently: "It’s our 20th anniversary this year – this would be the perfect year but places get booked out, so what we’re hopefully doing is planning on doing something to celebrate next year.

"It’s something that we want to do and it’d be nice to celebrate and give thanks to all the fans. I’m not getting any younger. Let’s hurry up and get this done."
