Water babe: Holly dazzles with a sleek new look

The former underwear model, whose plunging necklines on Dancing On Ice have raised more than the odd eyebrow, said she had managed to wash her hair in three minutes.

She went on: "The average is about seven minutes for men and about 7.2 minutes for a woman so it's not that much difference. Every minute you spend in the shower you use nine litres of water.

"Aim for the optimum three-minute shower then you're going to save a lot of water.
