Donna Mills is proving age is just a number.

The 85-year-old “Knots Landing” icon is taking fans by surprise with her latest career move — joining OnlyFans.

The actress, who became a television sensation playing the glamorous and ruthless Abby Cunningham on the hit show, said the platform will give her a chance to connect with fans in a more personal way.

“I’ve always appreciated the incredible support and encouragement I’ve received from my fans over the years. Social media has been a wonderful way to stay connected, but I’m excited to join OnlyFans because it offers the opportunity for a more personal and direct connection,” Mills told Variety.

Mills said fans can expect an authentic look at her life off-screen.

“I’ll be sharing moments from my daily life, behind-the-scenes glimpses, and engaging with fans in a more meaningful way,” she said. “It’s simply another platform to spend quality time with the people who’ve supported me throughout my career while staying true to who I am.”

OnlyFans executives noted the Hollywood veteran isn’t switching up her image.

“This is not about changing who she is. It is about giving her longtime fans more access to the personality, style and behind-the-scenes moments they already love,” Andy Bachman, CEO of OnlyFans owner Creators INC., said.

“Donna has always been fearless and ahead of her time. She told me, ‘YOLO — let’s do it,’ and that perfectly captures her attitude. She is approaching OnlyFans on her own terms and creating a space that feels authentic, personal and completely true to her.”

The announcement comes just weeks after Mills shared the habits she credits for looking and feeling her best at 85.

“I think the people out there have to realize it takes work. You can’t just decide, ‘Oh, I’m going to look good,’ you know?” Mills said on Kara Mayer Robinson’s “Really Famous” podcast. “I didn’t wake up looking like this.”

The actress said she works out almost every day and regularly plays tennis, adding that a lifetime of exercise has helped her avoid many of the physical ailments that often come with aging.

“I started out as a dancer, so I know how essential that is, and I know what it means for your body,” she said. “And I know that I don’t have, at my age, any of the things that happen to the body, you know? I mean I’ve not had any knees replaced or hips replaced or anything, you know, because I never stopped working out.”

Mills also urged people not to give up on fitness as they get older.

“And so, for years they don’t work out,” she said. “You can’t get that back. You really can’t. You can start to work out again … but you’ve lost something in that time.”

Mills rose to fame on “Knots Landing,” starring on the long-running series from 1980 to 1989. With her signature blonde hair, bold fashion and stellar performances, her character became one of television’s most memorable soap opera villains.
