The 73-year-old actress, known for her role as Bond girl clairvoyant Solitaire in the 1973 James Bond film Live and Let Die, made the announcement after sharing she had the best sex of her life with his friend John Zambetti.
She told Page Six: "Life goes on and I don't think there's an expiration date for women unless they choose to. A lot of people say, 'Don't you wish you were younger?' And, in a funny way, no, because I've gained so much experience, I've had such a rich life, and I've made so many friends and so many extraordinary experiences. My life is very full now and I hope I'm wiser."
The "Dr Quinn, Medicine Woman" actress revealed earlier this year that she enjoys dating musician boyfriend John, 74, for their bedroom antics.
In an essay for Cosmopolitan's Sex After 60 digital issue, she says:
"Sex right now is more wonderful and passionate than anything I remember because it's based on trust, love and experience. I know myself and my body now, and John has had his experiences in his life - it doesn't work out like when you're younger".
