Comedian and actress Magda Szubanski will today announce she is gay, as she joins the push to legalise same-sex marriage in Australia.
Ms Szubanski, 50, will discuss her sexuality for the first time on television tonight.
Yesterday, the Kath and Kim star released a statement saying she was "1000 per cent" behind a push to legalise same-sex marriage, and that laws prohibiting it were unfair.
"We pay taxes, fight wars for this country, nurse you when you are sick, make you laugh, sing and dance for you, play netball for you, star in your movies, cook your meals, decorate your store windows," she said.
"And, chances are, gay people designed whatever it is you're wearing.
"All Australians, including gay Australians, should have exactly the same rights, including the right to love, marry and take care of our partners.
"The law means that you could be a serial killer and have killed all of your spouses and yet you would still be considered fit to marry," she said.
Ms Szubanski has appeared in some of Australia's most popular comedy shows, including the D Generation, Big Girl's Blouse and Kath and Kim.
She also won many hearts when she went public with her weight loss campaign as the face of Jenny Craig.
In parliament yesterday, two independent MPs lodged private members bills attempting to redefine marriage in Australia as a union of two people, rather than between a man and a woman.
