Funny joke.
The lesbian part might come as a shock to her husband. :)
In 2008, Sia discussed her sexual orientation in interviews with Scotland on Sunday and AfterEllen.com,[77] and announced her relationship with JD Samson; they later broke up in 2011.[78][79] She was included on a list of gay entertainers in the June–July 2009 issue of The Advocate.[80] In both 2009 and 2010, Sia was nominated by readers of SameSame.com.au as one of the 25 most influential lesbian and gay Australians.[81][82] When asked about her sexuality, she said, “Before I was actually successful I’d always said I’ve always dated boys and girls and anything in between. I don’t care what gender you are, it’s about people. I didn’t just recently open up, I just recently got famous! I’ve always been... well, flexible is the word I would use.”[83]
Sia has suffered from depression. She has said that she suffered from addiction to painkillers and alcohol, and had also contemplated suicide before, going as far as writing a suicide note
