Alexa followed suit with her heartfelt tribute: "Happy Birthday To This Ever-Beautiful, Pure, N’ Precious Mother O’ Mine… Who Always Feels Like Home To Me.

In a recent interview with People magazine, Brinkley opened up about her secret to maintaining her youthful appearance over the decades since rising to fame in the 1970s.

Acknowledging her approach to aging gracefully, the actress revealed that she is comfortable with embracing a few lines here and there. While Brinkley confessed to having experimented with Botox in the past, she expressed a preference for avoiding excessive alterations to her appearance.

The focus of the discussion shifted towards the concept of looking fabulous while allowing oneself to age naturally.

"I want to accept certain wrinkles. That's the way I'm approaching aging," Brinkley explained, emphasizing her desire to maintain a sense of authenticity in her appearance.

Expressing her concerns about going overboard with cosmetic procedures, Brinkley added, "Sometimes when people get older, and they overdo it, they can look waxy and — I don't know what the word is — preserved or something. I want a little life to show on my face, you know?"
