The entire video for Break The Ice will be computer-animated.
'When Britney came up with the idea of having a cartoon of herself in the video, it was a big relief,' a source tells the Daily Mirror. 'Now she's free to just concentrate on getting better.'
But Brit, 26, has agreed to film a cameo role as a love-struck receptionist for US sitcom How I Met Your Mother.
'Britney's not playing a version of herself,' show creator Craig Thomas tells Us Weekly. 'I think that's part of what appealed to her.'
Break The Ice is released on 14 April.
