With sparkling eyes and a healthy glow, Simone Callahan looks like she has discovered a fountain of youth without resorting to plastic surgery, extreme dieting or fake tan. Just back from a relaxing private yoga retreat in Bali and sporting a golden tan and a big smile, Simone looks more like a model than a mum of three, but then she freely admis she is the happiest she has ever been. “I wish Shane nothing but luck,” she says.

The man putting the smile back on Simone’s face is hot model and sales executive Toby Roberts, who swept her off her feet when she least expected just after Shane was caught out with Liz. “My confidence took a beating,” Simone admits. “Toby definitely rescued me at the right time in my life. There was a lot going on in my head at that time and my confidence was totally shot… and still is to a certain extent. “But he is such a genuine person, so positive with a very good nature. He’s very strong – which I like – and he makes me laugh. There’s lots of magic there.”

While Shane and Liz have been parading their love for the whole world to see on Twitter, at events and in interviews, Simone has tried to keep her own love life out of the spotlight. The romance would never even have begun if it weren’t for Toby’s step-sister Shara, who is also a close friend of Simone’s, “playing cupid” to get Toby and Simone together. But even after the first sparks started to fly, she and Toby were determined to take things slowly and let their relationship blossom, rather than rushing into a longer term commitment.

Toby even admits he initially felt Simone may have been on the rebound. “I didn’t want to plunge headlong into things because I knew you and Shane were very much together late last year,” he said. “I thought it could have been a rebound situation!” But he could not have been further from the truth.
