United Kingdom, Sept. 10 -- Sharon Stone has been "celibate for quite a while now".

The 68-year-old actress has revealed while she is "a really good girlfriend" in relationships, she has had "no luck at all" recently as her priorities have shifted.

She told Mayim Bialik's Breakdown podcast: "I'm a really good girlfriend, but I haven't been a girlfriend in a long time.

"And I've been a girlfriend to bad boyfriends, and I've been a girlfriend to good boyfriends. I've had good luck and bad luck and no luck at all.

"For quite a long time I've had no luck at all. I've been celibate for quite a while now because I'm just at the point where I really only want to be with someone that I care for."
