Turning 40 is a big milestone in a woman's life as her body undergoes many changes physically which leads her to many hormonal changes.

Post 40 years of age, a woman's body gets ready for menopause too. If we look at our celebs that are now past 40 (or even 50, or 60 years) of age, we don't see any such signs! Take a look at few celebrities who are in their 40s, 50s or even 60s and still look like a rock star.

Do you remember Brooke Shields from "Pretty Baby" who was famous for her bushy eyebrows and stole the heart of the then tennis heart throb Andre Agassi? She is now 48 years of age and still looks gorgeous! So does former Mrs Kutcher, Demi Moore, who will turn 51 in November. Demi flaunts her great bikini body in most of her selfies she posts of Twitter. Isn't it amazing?

Next is our former Spice Girl Geri Halliwell. Remember the redhead-turned-blonde beauty amazing us with superb dance moves in "It's Raining Men" back in the 90s? The mother of a toddler has turned 40 some time back, and you will be surprised to know that the singer still has toned bikini body up to this day.

Former actress, Goldie Hawn, is not 50 but 67 years of age and is an image of poise and beauty. The way she carries herself at this age is remarkable. Have a look at her photos and see yourself.

And one that cannot simply be excluded in the list are Halle Berry and Heidi Klum. While the currently pregnant star, Berry, is 47 years old, Klum is 40 and both have a fantastic body during this age. Both women have striked back after giving birth and have always worked hard to achieve their ideal post-baby bodies..

Queen of Pop Madonna is also in her 50's but she is fit as if she's only in her 20's. The iconic singer puts in a lot of hard work to get those looks by doing Yoga, Pilates, eating right and even with the help of plastic surgery. Whatever hard work goes into the killer abs is worth it as we always see Madonna in her best looks even at this age.

"Eyes Wide Shut" actress, Nicole Kidman, has always been slim and displays a certain charm and poise in her looks. You will be amazed to know that this Aussie actress is now 47 years of age and still looks as hot as she does in her movies when she was younger.

"Paradise" and "Private School" actress Phoebe Cates use to play all high-school oriented roles in her movie carrier. She looked great then and even now when she turned 50! Have a look at her pictures to believe it.

Another surprise package is Mexican actress, Salma Hayek, who is 46 years of age and does not even look half of it. Hayek has always been known for her curves, and she still loves to flaunt them until now.

If we are talking about women in 50s and beyond, how can we forget the great Sharon Stone? The "Basic Instinct" actress is now 55 and still makes us remind of her famous legs crossing and uncrossing scene from the movie.

"Sex and the City" actress, Sarah Jessica Parker, is now 47, many are in awe at the way the star has carried her body and figure at this amazing age. Other actress falling in this club is the ageless beauty Julia Roberts, who turned 45 and still dons the qualities of a "Pretty Woman."

How can we forget "As Good as it Gets" actress, Helen Hunt, who is now 50 years of age and loves to post her beautiful pictures on Twitter?

And last but not the least is Jennifer Aniston, who is 44. Aniston looks amazing as she always did in the past decade 10. She does this by taking care of her body by eating working out right.
