Simone Callahan's sizzling body at 41!

She’s never looked better… and Simone tells Woman’s Day it’s all thanks to her new man Toby Roberts. She shows off her hot bikini body on a holiday in Bali.

With her skin glowing and blue eyes sparkling, Simone Callahan laughs when asked what sort of diet and exercise plan she relies on to look so good. “I’m not into diets,” the mum-of- three insists, instead attributing her renewed vitality to boyfriend of 12 months, Toby Roberts.

“Toby has always been big on eating well and that has probably rubbed off on me. “We both love the occasional chocolate, and I’ve always loved sweets, biscuits and lollies – probably too much!” How then does she keep in such great shape at 41? Friends would say it’s a “love diet”, with Simone the happiest she’s been in years since falling in love with model and business executive Toby, 37. “I don’t have much discipline when it comes to food,” she says.

“If I’m hungry, I like to eat, so I think a diet would kill me. “I’ve also been doing yoga on and off for eight years,” Simone explains. “And I know I shall be doing it the rest of my life. It’s almost addictive. “I started with iyengar yoga and changed to ashtanga 18 months ago. It’s a very disciplined yoga and I’ve been averaging about five sessions a week.” Simone credits yoga with helping her through the tough and turbulent times in the latter part of her 10-year marriage to Shane Warne, and the 18 months after they reunited.

“Yoga makes me feel very calm, centred and at peace with life,” she says happily. “It has been a great way of letting things go.” While Toby is dedicated to health and fitness, Simone has also been encouraging him to explore yoga. “Toby does cross training,” she explains. “He doesn’t like the gym environment. He prefers to be outside surfing, swimming, running and cycling as much as he can.”
