Age is just a number. It's not just a saying but a reality as there are growing numbers of celebrity women who proudly flaunt their well-toned bodies in skimpy bikinis when most of other women in same age group are dealing with menopause! From Julianne Moore to Sharon Stone, these women have surpassed the age barrier and still make jaws drop by how fabulous they look.

Below is a roundup of the best post 50 bikini-bodies in today's times.

Demi Moore: Demi Moore just turned 50 but her body fails to age. The "Indecent Proposal" actress, who has endured a hard time since splitting from much younger husband Ashton Kutcher, 35, seems to have let bygones be bygones. The sexy brunette was rather spotted working out with her eldest daughter Rumer, 24. The mother of three had a good time with friends in Malibu sun at her ex-boyfriend Harry Morton's home in May this year where she donned a pink bikini.

Sharon Stone: It's been more than 17 years since Sharon Stone made guys drool in "Basic Instinct" by her crossing and uncrossing of legs but at the age of 55, she still has no qualms about showing off her well-toned body in a bikini. The "Basic Instinct" star was spotted in Italy enjoying some down time on a break from filming her new Italian film called "Un Ragazzo D'Oro," which translates as The Golden Boy.

Christine Brinkley: Christine Brinkley is 59 but doesn't look like it. Brinkley gained worldwide fame beginning in the late 1970s with three consecutive "Sports Illustrated" Swimsuit Issue covers through 1981 but this almost 60-year-old blonde bombshell stunned everyone in a new sexy swimsuit spread in Haute Living New York's June edition.

Julianne Moore: This is one actress that fails to age. The 52-year-old enjoyed a dip in the sea on a holiday in Hawaii with her family in January this year and showed off her curves in a black halter neck bikini top by Melissa Odabash and a pair of shorts. Surprisingly the actress is not a bikini fan. "I don't believe it (bikini) makes people look better. I think it just makes them look like they had something done to their face, and I don't think we find that instinctually appealing," the "Boogie Nights" actress told Daily News online.

Kathy Griffin: American actress and comedian Kathy Griffin often posts her pictures of her shapely legs on Twitter and at age 52 proudly shows off her bikini body. "I swear I haven't had anything in years! Promise. No Botox, fillers, nothing!" Griffin wrote on Twitter squashing rumours of her going under the knife.

Kim Cattrall: Kim Cattrall is known for her role as Samantha Jones in the HBO comedy/romance series "Sex and the City" but she is also equally famous for her bikini body at age 56. However the body like hers is not easy to maintain as the actress recently confessed she has been on diet since 1974! "I take care of myself, which includes dieting, exercising and minimising stress. I joke that I've been on a diet since 1974, which is basically true," Cattrall told Woman & Home magazine adding "I like to eat, and my body type is not naturally this thin, especially at this age. So I do watch what I eat and drink but I'm not obsessive -- it's just a way of life."
