Donna Mills has joined OnlyFans at the age of 85.

The Knots Landing actress - who became a household name in the 1980s playing the glamorous Abby Cunningham on the hit TV series - signed up for an account on the adults-only subscription platform so she can connect with her fans in a more "personal and direct" way.

She told Variety: "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.

"I'll be sharing moments from my daily life, behind-the-scenes glimpses and engaging with fans in a more meaningful way.

"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."

And the Joy actress won't be changing who she is to fit in on the platform.

Andy Bachman, CEO Creators INC, said: "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.

"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."

Donna recently revealed she still works out almost every day and plays tennis often, which she thinks has helped her avoid many common ailments people experience as they get older.

Speaking to Kara Mayer Robinson on her Really Famous podcast, she said: "I think the people out there have to realise it takes work. You can't just decide, 'Oh, I'm going to look good,' you know? I didn't wake up looking like this.

"I started out as a dancer, so I know how essential that is, and I know what it means for your body.

"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."

The Nope actress stressed the importance of regular exercise at every age.

She said: "And, so, for years they don't work out. 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."
