Christie Brinkley celebrates 65th birthday in a sexy minidress: 'Do you ever age?'

Christie Brinkley is just days away from turning 65 on Feb. 2, but she’s already kicked off the birthday celebrations — and kicked up her heels.

Looking more supermodel than senior citizen, Brinkley wore a metallic minidress that showed off her long legs for an early birthday party hosted by Ultherapy, the nonsurgical skin-tightening and lifting procedure. Brinkley is fronting the company’s “Milestones of Me” campaign, which encourages women to celebrate the important moments at every age.

The model’s older daughter, singer Alexa Ray Joel, performed “Happy Birthday” for her mom, who sported gold high heels and long blond waves for the occasion.

“As I approach this milestone birthday, I look back on all that I’ve learned and the things that have become important to me, not only as a mother and friend, but also as a woman,” Brinkley said in a press statement. “For me, it’s not just about the big birthdays — it’s the smaller, more personal moments, like when my garden blooms in the spring, that deserve celebrating.”

Her fans, meanwhile, are celebrating her stunning look.

“Do you ever age!? No!” gushed one commenter.

“Your dress!!!!” raved another fan.

“Happy birthday to the most beautiful supermodel that never changes,” read another comment.

While many followers singled out her “great” legs, a few trolls couldn’t resist taking a potshot.

“That dress is a bit [too] short,” one remarked.

“Could your dress be any shorter!” another commenter wrote, prompting one of the supermodel’s fans to fire back, “I think it could — with those legs, why not? Just incredible!”

Hey — it’s her party and she’ll flash some leg if she wants to.
