These days, Brinkley is booked and busy in her older age, from launching a clothing line with HSN to getting a feature in Sports Illustrated Swimsuit’s 60th Anniversary issue.

However, there was once a time when she thought she’d be “chewed up and spit out” of modeling by the age of 30 because she was told so.

"Fifty isn't 50 anymore. Thirty isn't 30 anymore,” she told PEOPLE exclusively in June when she launched a clothing collection with HSN.

"It's the start of a great decade," she said of entering a new decade. "I'm hearing from women on my Instagram, like, 'Now I'm looking forward to my 7-0. I was kind of dreading it, but you're making it look so fun. And it is really important to make it fun and so far so great."
