Amerie at The annual Girlguiding UK Big Gig, a special concert organised solely for members of the UK Girlguiding organisation held at The Manchester Evening News Arena, Manchester, England - 13.10.07

The Toxic star was criticised following her performance of comeback single Gimme More at last month's (Sep07) MTV Video Music Awards, but Amerie believes Spears needs to revisit the energetic dance numbers of her early hits to get back on track.

She says, "I like her new single Gimme More, but I think something with really high bursts of energy would have been cool for her. She needs to move more."

And Rogers admits she is keen to work with Spears in the future, adding, "If she wants to do something I would totally be there. If we did I'm sure it would be great and a lot of fun. I think she is a sweet girl."
