Who are you calling grandma?
Save for a few faint wrinkles, these celebrities are putting women half their age to shame with their sexy images.
So what is the secret behind their seemingly everlasting youth?
CHRISTIE BRINKLEY, 60
Last week, the blonde US model showed off her eye-popping figure - gravity-defying breasts, toned legs and flat tummy - in an orange Victoria Beckham bodycon dress at a party celebrating the 50th anniversary of the Sports Illustrated Swimsuit Issue in New York.
Brinkley rose to fame after appearing on Sports Illustrated cover for three consecutive years and being cosmetics giant CoverGirl's face for 25 years.
The self-proclaimed bikini-shy mother-of-three wore a blue swimsuit for the cover of People magazine.
She also sauntered in a two-piece for Air New Zealand's in-flight safety video.
Senior editor of Sports Illustrated's Swimsuit Issue MJ Day gushed to People magazine: "She looks phenomenal. She has the legs of a 30-year-old and the face of an angel.
"She's what you aspire to look like at 60. She's mind-blowingly beautiful."
l Exfoliating daily
l Hair extensions
l Total Gym (home gym exercise equipment)
l Spinning, running, weight-lifting and yoga. Leg lifts while brushing her teeth
l A mostly-vegan diet of three meals daily, snacking on melon and walnuts
l Visits the dermatologist once a month for "special facials"
l "Never say never" to plastic surgery, which she has neither confirmed nor denied doing
"I don't believe in allowing my age to define me. And I really believe attitude plays a huge part in how you feel.
"The word 'involved' has a lot to do with feeling young. It would be remiss of me to not say that one of the best is to care about the world around you when talking about beauty secrets."
JANE SEYMOUR, 63
The former Bond girl and mother-of-four flaunted her toned bikini bod for the cover of US magazine Closer Weekly's January issue.
She has admitted to - and regretted - plastic surgery in the past, but these days, she lets nature take its course, does her own make-up and eschews facials.
l Eating organic food and whatever she plants in her garden
l Spinning, pilates, gyrotonics and light weight training three days a week
l Wear a hat while out in the sun, drink lots of water and get plenty of sleep
l Botox injections, breast implants and eye-lift in the past
"I'm in better shape now in some ways than I was when I was doing the Bond film (1973's Live And Let Die). I don't do major fasts or work out crazily every day. I hope I can inspire people!"
SHARON STONE, 55
The US actress and mother-of-three appeared on the cover of Shape magazine's March issue looking toned in a yellow bikini under a mesh cover-up.
Although she has resisted many surgeons' attempts to give her a face-lift, she admitted to grappling with the ageing process.
Stone, who suffered from depression in her 20s after a 20kg weight gain, told Shape: "There was a point in my 40s where I went into the bathroom with a bottle of wine, locked the door and said, 'I'm not coming out until I can totally accept the way I look right now'.
"And I examined my face in the magnifying mirror, looked at my body and I cried. Then I told myself, 'You're going to get old now. How do you want to do that?'"
l Avoid alcohol and processed food
l High-protein diet heavy on steak, fish and cheese
l Strength-training, stretching, dancing and yoga
"This idea that being youthful is the only thing that's beautiful or attractive simply isn't true.
"I don't want to be an 'ageless beauty'. I want to be a woman who is the best I can be at my age."

PAT KRAAL, 51
The former Singapore supermodel, groomed by Carrie Models in the 80s and took off for Paris at the age of 20 after which she landed her big break modelling for fashion house Givenchy, looks like she never left the industry.
Her lithe figure and youthful appearance betray the fact that she is mother to four children aged 13 to 22.
She credits everything to good genes since she does not follow any strict diet, skincare or exercise regime.
Kraal is of Thai, English, Portuguese and Dutch descent, stands at 1.78m, weighs 56kg and has enviable 32-26-36 statistics.
The Paris-based model scout, who recently returned to the workforce after 21 years as a housewife, told The New Paper: "Most women my age hate me because I eat anything and everything."
But don't expect her to don a swimsuit for a magazine cover anytime soon.
"It's all for publicity," she said, referring to the latest images of Christie Brinkley, Jane Seymour and Sharon Stone.
l Anti-ageing and pharmaceutical skincare products
l Drinking lots of green tea
l Walking, housework and taking care of her children
"Being part Asian, most people think I'm in my 40s and my children are always proudly telling me that their friends say I'm so young and 'trop belle' (too beautiful in French).
"Several men and women have come up to me to tell me how beautiful I am, which always makes my day."
TAN KHENG HUA, 51
The local actress had shattered all stereotypes of auntie-dom when she participated in the Celebrity Pole-Off competition to raise funds for charity in 2012.
Tan hasn't looked back since.
In fact, she'd rather be in her 50s than her 20s because the latter was "a time of tough decisions". But even back then, she knew that she wanted to "grow old looking fit" without extracting the joy from the process.
Like Pat Kraal, dieting and exercising aren't exactly a priority for the mother of a 16-year-old girl. Forget beauty regime, too.
"If I had not been sponsored by (local medispa skin specialist) Vedure Mediboutique, I don't think I would even go for facials at all," said Tan, who's 1.58m tall, weighs 46kg and has vital stats of 33-25-33.
"I would never queue for food, nor would I drive out just to taste something."
As for cosmetic surgery, Tan would rather "use the money for a fabulous skiing holiday".
And if she was ever invited to grace a magazine cover in her swimsuit, the self-proclaimed liberal "delinquent parent" says "she would jump at the opportunity" if it "represents a philosophy that I uphold"."
l Diving, skiing, yoga - "anything to do with balancing"
l Avoiding sweet drinks and alcohol
l Cashews, pistachios and Brazil nuts
"It's important to be happy in your own skin, especially when it comes to physical activities. Do it if you enjoy it."
