The video shows a toned Brit working the floor with her backup dancers. The hair is still done up with extensions, but the abs are very real.

Meanwhile, Toxic singer Britney has won MTV Video Music Awards. She took Best Female Video, Best Pop Video and Video of the Year honours for her hit track Piece of Me.

Britney hosted the VMA ceremony in Los Angeles with British comedian Russell Brand, who drew fire for criticising the Jonas Brothers’ commitment to chastity and calling US President George Bush ‘that retarded cowboy fellow’.
