It's Melanie Brown, best known as Scary Spice from the Spice Girls pop group!

Also known as Mel B, this pop sensation has appeared in various musical works and shows like 'The X Factor Australia', 'The X Factor UK', 'America's Got Talent' and 'The Voice Kids Australia' as a celebrity judge. She's always doled out her advice and critiques, but we also love her for her incredible body. The 39-year-old megastar is definitely one of the top girls on our list.
