Iconic model Christie Brinkley is celebrating her 65th birthday, but she's not letting her age define her. On Saturday, February 2nd, she wants everyone to know that age is just a number, and she continues to look and feel younger than her years would suggest.

At a birthday bash held in her honor at the Gramercy Park Hotel on January 29th, Christie, who's also an actress and businesswoman, joked about her age, saying, “Groundhog’s Day is my birthday, and I’ll be turning 50 for the 15th time.” According to People, Christie went on to say, “Everyone focuses so much on your age number. I prefer to say, ‘That’s just my biological age, but my spirit age is something entirely different.’ Your spiritual age reflects who you are as a whole person, not just this assigned number based on how long you've been living in this crazy world.”

Staying Youthful: Christie's Take on Aging Gracefully

Christie Brinkley is no stranger to defying the expectations of age. She continues to look younger with each passing day, but she's also aware of the immense pressure that comes with maintaining that youthful appearance. At a recent cocktails and conversation event for her new show, American Beauty Star, held in New York City, Christie opened up to Closer Weekly about the pressure of always looking her best. “I’m in a position where I’m expected to look good for my age all the time, but eventually, age catches up with everyone,” she shared. “I don’t want to be anything other than who I am.”
