Just two days before her milestone birthday on February 2nd, Christie celebrated with friends and family at her birthday bash in a gold sequin minidress and gold pumps. The soire was hosted by Ultherapy, a non-invasive skin-tightening procedure. (Christie is the face of their new campaign.)

As I approach this milestone birthday, I look back on all that Ive learned and the things that have become important to me, not only as a mother and friend, but also as a woman, Christie said in a press release for the campaign. For me, its not just about the big birthdaysits the smaller, more personal moments.

And she was sure to celebrate those, too. In her Instagram caption, she gave a shout out to her daughter Alexa Ray Joel who serenaded her mom with Happy Birthday.

And even though shes almost 65, Christie probably wont be retiring the many other factors (other than immaculate genes) that she can credit for her youthful looks, including:

"I would say running is my favorite way to sweat, but Im not really supposed to do that anymore because of injuries," Christie revealed to The Cut . To go easy on her body, she'll walk along the beach and move her arms as if she's swimming, or pick up and carry rocks along the way.

Christie told The Cut , she uses the home exercise machine for which she's a spokeswoman-she's even developed some of her own moves according to the machine's website . Even if she's only got seven minutes, she'll use the time to go for a quick run on the machine.

3. Tough coaches

To keep those legs toned, Christie also has drill sergeant spin instructors to thank. I love spin instructors. Yeah, sometimes you need a little drill sergeant to inspire you and keep you going, she told Women's Health .

Christie told InStyle , about how she keeps fit with her daughter sailor who loves being outside. We live by the water, so Ill kayak and paddleboard with her too, she explained.

Christie told Women's Health that she thinks a balanced diet is key. "Even on a low-carb diet , you should be able to like, live it up," she added.

6. A vegetarian diet

Shes been a vegetarian since she was 13. I love animals. I do not want to take part in this barbaric system, she revealed to WH. She also raised her kids to keep away from meat, and shes got no regrets about it.
