Sugababes star Keisha Buchanan has accused Britney Spears' management team of 'exploiting' the troubled singer. The Round Round hit maker insists Spears is unfit to be promoting her comeback album Blackout, and singles out the star's performance in the video for single Gimme More for criticism.

Buchanan believes Spears' label bosses are to blame for the star's 'soulless' appearance in the footage - and are risking her health and well being by forcing her to promote her career.

She says, "Whoever put Britney in that new video should be ashamed. The way she looks at the cameras petrifies me. She's got dead eyes. She shouldn't be there."
