The British singer moved to Los Angeles and took part in the hit U.S. reality show in 2007, coming second in the competition.

She headed Down Under last year (11) after landing a judging job on the Aussie arm of Simon Cowell's The X Factor, and now TV bosses have hired her to host the celebrity dancing contest.

Brown says, "Doing Dancing with the Stars in America changed me. I've danced all my life, and, of course, with the Spice Girls, but there was something so intoxicating about learning to dance in such a classic, trained way. It was intense, but I loved every moment. I'm still annoyed I didn't win!

"As any contestant on DWTS will tell you, it does change your life. I will be bringing my experiences to the show, and will be very protective of this year's group."

Brown hinted she's considering a move to Sydney after admitting she had fallen in love with the Aussie way of life.
