Singer and television personality Melanie B has revealed that unlike her Spice Girls nickname, she is actually pretty tame. 

Speaking to EWeekly.com, the Spice Girls star joked that although her nickname of Scary Spice suggests she's intimidating she really isn't that frightening at all:

"The scariest thing about me, I think, is probably that I'm unpredictable. You don't know what you're gonna get and when you're gonna get it!"

This year also marks the 20th anniversary of her girl group and she confessed that she does miss the other girls and often reminisces about the fun they had together: "It's funny; there have been a few Spice themed segments in the auditions [for America's Got Talent], and it always makes me go 'Awww, I miss my girls."

Earlier this month, she suggested to Smashing Interviews magazine that a reunion might be something that's on the cards in the future: "I think all of us are interested. We started this group almost 20 years ago, and we launched on the scene together. So we've all got a mutual respect for each other, but we'll see. Nothing has actually been set up yet [regarding the rumoured Las Vegas shows]."

"We've been in talks about doing something together at some point, but there have been no dates, no confirmation of anything really. It's just a conversation."
