Speaking to PrideSource, the actress, who has only had public relationships with men, said she was taking a fluid approach to her sexuality.

"My sexual orientation is up for grabs, I guess you could say," Sarandon, who has been a long-time campaigner for AIDS education and marriage equality, said.

She went on to lament our modern-day concern with defining sexuality so rigidly, explaining that in the 1980s she "did not think you had to declare yourself as rigidly as you do now in terms of having to declare yourself almost politically about your sexual preference".

The Rocky Horror actress added that she had previously had a relationship with gay actor and her The Hunger co-star, the late Philip Sayer.

"I did at one point have a very successful and very loving and wonderful affair with a man who then wasn't with another woman after me, and that worked out fine!" she said.

The comments come in the same week as Sarandon's appearance on MSNBC's All in with Chris Hayes in which she re-affirmed her reasons for not supporting Hillary Clinton's campaign, and reasoned why she would not end up on the wrong side of history following the election of Donald Trump to president.

"If you are not in touch with the status quo, you are going to lose," Sarandon said, "I mean, if you're arguing for shoring up the status quo, when America is asking for change, you are going to have a difficult time." The views echoed a previous interview Sarandon gave on the show last March where she said "Some people believe Donald Trump will bring the revolution immediately," appearing to argue that Donald Trump would shake things up.

"[W]hat we have now is a populace that is awake," she said.

Susan Sarandon married Chris Sarandon when she was just 20. They divorced 13 years later, with Susan retaining his surname for her professional work.

Since then, Sarandon has been romantically tied to Italian filmmaker Franco Amurri (with whom she shares daughter, actress Eva Amurri) and David Bowie.

She was in a relationship with actor Tim Robbins for 23 years

After ending things with Robbins in 2009, Sarandon was rumoured to be romantically linked to Jonathan Bricklin, who was her fellow investor in New York ping pong bar, SPIN, however the couple never confirmed their relationship and Bricklin is now dating Pablo Picasso's granddaughter.
