Kelly, at 34 still very much at the top of her game, said: “I’ve been training with Ashley Boden. I’ve felt incredible for it, so strong and sexy.
“My sex drive went up 100% – I think it’s the hormones and testosterone from the weightlifting.”
The newly engaged star’s transformation has not shed inches from her shapely hips and thighs.

Ms Brook is relatively old for a model, but proving she’s still at the top of her game after securing the cover of this month’s Cosmopolitan Body.
Far from being apprehensive about the ageing process, Kel is embracing maturity and the confidence it brings.

“You start enjoying life, sex and your body – and you know how to use it.
“Once you do that, that’s when people are drawn to you. That’s the most attractive thing.”
