The Spice Girls' debut single 'Wannabe' turns 20 next year - which makes us feel very, very old indeed.

However, the anniversary may well coincide with the girl group getting back together, if Mel B has anything to do with it.

Scary Spice was on The Tonight Show with Jimmy Fallon the other night, and revealed that she'd left space in her diary next year for a reunion. ""When you say it's our 20th anniversary coming up, it does make you think, 'Oh, my gosh, it really has been that long'. Hopefully, we'll gather the troops around, and we'll get to do something to celebrate it next year. It's in my plan, I don't know about anybody else's."

The last time the Spice Girls performed together was at the closing ceremony of the London Olympics in 2012. 

Mel B's comments follow on from those of Emma Bunton, aka Baby Spice - who also expressed her enthusiasm for a 2016 reunion earlier this year.
