I can see Sam's concern.

After watching the vid for HIAM, and there being so many stiff movements, I'm not holding my braath.

The video for HIAM was said to have lots of hard dancing, and none of that was present.

I would advise Britney not to dance in heels, and just stick to gym shoes. She is not Beyonce, therefore, she cannot dance in heels.

She better be wearing gym shoes in the upcoming vid.
