intro: Fifty is hotter than ever, and a slew of celebrities turning 50 this year are here to prove it.
Some of the biggest names in Hollywood are celebrating the big 5-0 this year.
Sandra Bullock is the latest.
"I don't know if it's the best place I've ever been, but it sure feels good," Bullock told Extra about approaching the milestone birthday.
The "Gravity" star, who turned 50 Saturday, had a good time celebrating too. She kicked off the festivities last Thursday at the Million Dollar Cowboy Bar with Chelsea Handler and a group of girlfriends.
An eyewitness told ABC News that Bullock “came in with about eight friends, sat down and had a couple cocktails. They just enjoyed themselves. Nobody got up on the table and danced.”
But Bullock did join Handler and others later for a "cheeky" pose on her birthday.
The single mother of Louis has never looked better. She recently flaunted her gravity-defying figure in last year's blockbuster hit "Gravity" opposite George Clooney.
"She looks so amazing," Sharon Waxman, the founder and editor-in-chief of TheWrap, told ABC News after the film's release. "She told me that she worked really hard to look that good."
Bullock isn't the only one who seems to be turning back time. Check out these other celebrities who have or will reach the half-century mark this year.
quicklist: title: Wendy Williams text: Talk show host Wendy Williams celebrated her July 18th birthday days before Bullock's with Chaka Khan serenading her on the show with “I’m Every Woman." "Fifty has always been old to me until I got here," Williams told The Huffington Post. Then I look around and I see Vanessa Williams because she's a couple of years older than me, but I remember when she turned 50, I'm just like: 50 is really not your mother's 50 anymore."
quicklist: title: Courtney Love text: Courtney Love is still rocking on at 50. The Hole singer reached the milestone July 9 but didn't give it a second thought. “I look really good for my age, and I know it,” she told The Grid. “It’s irrelevant to me."
quicklist: title: Courteney Cox text: "Friends" alum Courteney Cox celebrated 50 June 15. Unlike many older celebrities that have sworn off Botox and plastic surgery, Cox has always been open about her fight against aging. "You know what, I'm game for anything. I'm very open to trying to prolong the inevitable," Cox, who has admitted to using Botox and lasers, told New You Magazine.
quicklist: title: Lenny Kravitz text: Another rocker still rocking on, Lenny Kravitz, who turned 50 May 26, has branched out into acting in recent years. The father of actress Zoe Kravitz was featured in "Lee Daniels The Butler" and the blockbuster franchise "The Hunger Games." His music fans will also be glad to hear he has another album coming out this fall.
quicklist title: Melissa Gilbert text: Harder even than our rock stars turning 50 is hearing that former child star Melissa Gilbert turned 50 on May 8. The "Little House on the Prairie" star acknowledged this, tweeting years earlier after getting trifocals, "This getting older business is not for sissies!!"
quicklist: title: Mariska Hargitay text: "Law and Order: SVU" star Mariska Hargitay couldn't wait to turn 50 on Jan. 23. “You name the feeling, I think I’ve had it about turning 50!” she told Closer magazine. And most of the feelings are upbeat: “Totally excited. Really proud. Hair on fire!”
quicklist: title: Russell Crowe text: The two-time Oscar winner Russell Crowe turned 50 on April 7. Having played lead roles as a younger man, he's realistic when it comes to aging. Last year, Crowe joked about his "creaky" bones and joints while prepping for the role of Superman's father in "Man of Steel," which required him to wear spandex.
quicklist: title: Rob Lowe text: Brat pack heartthrob Rob Lowe never seems to age, though he turned 50 March 17. "The candles on the cake mean absolutely nothing," Lowe told People magazine. "It truly is about how you lead your life and not how much life is led," he told People magazine
quicklist: title: Mary-Louise Parker text: "Weeds" star Mary Louise Parker turns 50 Aug. 2. The single mother of two -- she raised son William on her own after his father Billy Crudup left her seven months pregnant to be with Claire Danes and adopted a baby girl, Caroline, from Ethiopia seven years ago six years ago -- jokes about turning 50, saying she might take up weed then. "I was thinking of taking it up when I turned 50," she told Metro. "I think maybe that’s when I’ll become a big pot-head."
title: Keanu Reeves text: Like his "Speed" co-star Sandra Bullock, Keanu Reeves looks like he's hardly aged since then, though he's aware of the difference between now and then. He told Brazil's Globe Journal earlier this year, "It is clear that death can come at any time. There is more risk for disease. What has not changed is the pleasure of acting. I started at 15, but the euphoria is still with me.
