The Hangerover III actress has never married and sees no reason to
The actress has enjoyed several racy roles, including nude scenes in erotic 2002 thriller Killing Me Softly.
The stunning star is relaxed about sex and believes other women should also embrace this side to themselves.
“A man can be sexual and it’s OK. But if a woman is too sexy and sexual it’s not. I don’t think we have a healthy attitude in our society about women and sex," she explained to British newspaper The Sun.
“I guess I feel it’s important for a level of happiness for a woman. Women should enjoy and appreciate their sexuality the way they want and not be judged by society about it. It’s about having an acceptance and dealing in a healthy way about your own sexuality. If you look at people who are rigid about sexuality they are at the same time doing something dark on the side.”
The 43-year-old returns to comedy franchise The Hangover in the third instalment, reprising her sexy character Jade from the second movie.
Heather is also working on her own script, which aims to change the things about the film industry which she views as "sexist", such as the small amount of female directors.
“[The script] is actually about how hard it is to make movies about women. It’s all about my own frustration in the business, I guess," she revealed.
“The film is basically about sex and being a woman and dating and friendship. It’s really about how sexuality can be confusing as a woman - and also dating and stuff.”
The pretty star has had several famous boyfriends, including a relationship with the late Heath Ledger.
Heather has never married, but is content with her current situation.
“I feel I have a happy good life, so someone would have to make my life better. We’re not dependent economically on men, we’re free. You can choose to be with someone or to be on your own, and this is great," she grinned.
