1. Collagen Supplements

Holden loves taking collagen, both in skincare and in supplements. “As we age, the production of collagen slows and the collagen produced is less efficient – which underlies many of the changes we see with aging, such as wrinkling and sagging of the skin, joint pain, loss of height, and fractures,” says Deborah Lee, MD. “The structure of collagen is organized with a complicated fiber system, with chains of amino acids arranged in fibrils, like strong ropes, to provide a tight and reliable support structure.”

2. She’s a Fighter

Holden makes a point of forging her own path, no matter what. “Over the years, I’ve not changed but I have managed to change opinions,” she says. “I’ve been the same ever since I was a little girl – give me a chance and I’m going to prove myself to you. I never accept failure – in whatever I do.”

3. Balanced Diet

Holden doesn’t believe in restriction. "Life's too short to do fat-free, sugar-free, alcohol-free,” she says. “I don't believe in half-fat anything, I have full-fat yogurt, butter and cheese. And I splurge on the weekends. I love wine."

4. She Loves Being Outside

Holden is happiest when working out in the fresh air. “I’m an outdoor exerciser – I like yoga and running but it’s been too cold,” she says. “I’ve been put to shame by Alesha [Dixon, her fellow Britain’s Got Talent judge], who is working out and looking amazing, and by [daughter] Lexi, who has been really disciplined and got a little six-pack.”

5. She Embraces Her Age

“Who says that once you reach a certain age women have to dress a certain way, act a certain way? I don’t believe in those rules,” she says. “You do what makes you happy, what puts a smile on your face and, to be honest, you have got to an age where you care a lot less about what people think. I don’t care. I consider myself lucky to be following women like Kylie Minogue, Jennifer Lopez and Jennifer Aniston, who have really celebrated their 50th year by being grateful for their success, happy with their lives and still looking really hot.”
