We support her." Nicole's bandmate Melody Thornton added: "She's such a legend. She's making her way. And she's the Queen of Pop, along with Madonna, and we want to follow into those footsteps. So, we're excited."

Blonde beauty Ashley Roberts also recalled how the group first found out they would be performing for Britney.

She told MTV News: "Some of us heard on Halloween night. We were all in our costumes, and we're like, 'We're opening up for Britney Spears! That's so cool!' I think we all screamed and jumped a little bit!"
