Jackie O's swearing rant at producer

She's usually the well-composed co-host who balances out Kyle Sandilands' shock factor on air, but new audio of Jackie O reveals a fiery side to her.

During Wednesday morning's KIIS FM Kyle and Jackie O breakfast radio show, Kyle played an old, unheard snippet of audio of Jackie, launching into a swearing tirade at a producer.

Jackie is heard fuming and dropping the F-bomb left, right and centre, after the producers gives her the wrong spelling of some words for a spelling quiz on air. What's more, she bursts into tears and storms out of the studio.

"I don't know how many times I've gone though that, I'm sorry but that's just f**king pitiful," the mother-of-one says.

"It happens every f**king day. I am f**king upset about it, alright, f**king hell!"

"I've stressed this is really really important to me. That we don't get it wrong. I'm just so frustrated," she continues, before she starts shedding tears.

A producer suggests the radio star leave the studio and get some fresh air, and that's exactly what she does as she storms out.

On Thursday morning Kyle played this blast from the past for Jackie, and Jackie says the incident took place just before her daughter Kitty was born in December 2010.

"You had to be taken upstairs to be settled down," Kyle said.

Revealing she was pregnant at the time, 42-year-old Jackie admitted "I was a bit crazy during those days".

But according to Kyle, "the mics goes off and the real Jackie comes out".

Well, it's certainly a different side to Jackie, that's for sure!
