Pamela Anderson has said she finds Julian Assange "very sexy" fuelling speculation they are romantically involved.
Speaking on the popular Scandinavian chat show Skavlan, Anderson remained coy about whether she is dating Mr Assange, who is holed up in the Ecuadorian Embassy in London.
"Well he's imprisoned, that would be a little difficult", she said.
She went on: "Let's see what happens when he's free, but I spend probably more time with him than with any other man, socially, which is very odd.
"He's very sexy."
Mr Assange sought asylum in the Ecuadorian embassy in 2012, fearing he would be deported to Sweden to answer allegations of sexual assault. He claims he is innocent.
Mr Assange and Anderson are believed to have met for the first time last year, when she visited him at the embassy.
Rumours of a possible romance began when she posted on her blog: "My relationship with Julian - it's no secret.
"He is one of my favorite people - and he might be the most famous, most politicized refugee of our time. Famous for being persecuted. Famous for being persecuted is not a position of power but a position of vulnerability," she wrote.
"Julian is trying to free the world by educating it. It is a romantic struggle - I love him for this - He is the strongest person I know - but, living as he is, is very unhealthy, demeaning and inhumane."
Anderson, who gained fame as the star of the hit TV show Baywatch in the 1990s, has more recently focused her attention on humanitarian work and activism.
