Sia’s massive overshare on live radio

SHE might like to keep her private life to herself, but Aussie singer Sia has been caught sharing a little too much on a Brisbane breakfast radio show.

Sia had called in to Nova's Ash, Kip, Luttsy and Susie on Monday morning from Los Angeles and was discussing her favourite TV series when there was an audible flushing sound.

"Hang on, did you just take a piss?" Nova co-host David 'Luttsy' Lutteral interjected.

"Yeah, you heard me and I flushed too; I have no shame," Sia responded.

A confused Ash Bradnam said: "Did you really just go to the toilet while you're doing an interview with us?"

"I did. But guess what? Stars are just like us," Sia laughed, adding: "I've got to blow my nose now you guys."

The radio hosts were in hysterics as Bradnam joked, "Why don't you take a s--- and we'll get the whole thing".

"Unfortunately I don't need to take a s---," Sia concluded.

Sia was doing an interview with Nova 106.9’s Ash, Kip, Luttsy and Susie.

For the record, her favourite TV series include Netflix's Love on the Spectrum and The Fresh Prince of Bel Air.

The singer, whose movie Music is out next month, is known for wearing a wig to hide her identity.

The movie features dancer Maddie Ziegler, who appeared in her original music video for Chandelier after finding fame on reality series Dance Moms.

"It (the wig) is the best thing I ever accidentally happened upon," she told the breakfast radio show.

"The only thing lacking in the music industry was mystery and I needed to have a private life in order to be able to survive because I wasn't born for fame but I was born for singing and writing songs and it turns out now directing movies too."

Of Ziegler, she added: "I had thrown this 11 year old to the wolves and it made me feel like a pretty crappy person. I made it my mission to protect her."

Sia, who recently became a grandmother after adopting two sons, also revealed she has joined a "very stealth dating app" and logged into her Instagram for the first time in three years.
