Actress Michelle Rodriguez refuses to address constant rumours about her sexuality, because whether or not she is gay is "nobody's business".

The former Lost star has long been dogged by reports she is a 'closet' lesbian, but she insists she will never tell all about her private life, instead choosing to avoid speculation by journalists and online bloggers by imagining them as swine.

She tells Latina magazine, "I picture them turning into pigs, slime coming out the side of their mouth, and I picture them jerking off. I don't answer those questions.

“I just keep it to myself and it's nobody's business. If I wanna f**k a girl, a boy, a dog, that's my business. That's why there's bathroom doors."

And Rodriguez cannot grasp why the public want to know so much about her love life.

She adds: "What the majority of (people) want to know is what I'm doing with my vagina, and I think that that's sick.

"What do you care who I'm dating? I can tell when somebody just wants to know about sex. And it makes me sick."
