Radio queen Jackie ‘O’ Henderson cut a downbeat figure as she stepped out in Sydney on Saturday, as speculation swirls over tensions with co-host Kyle Sandilands.

The KIIS FM star, 51, appeared keen to go unnoticed as she shielded her face behind oversized dark sunglasses and opted for a low-key ensemble of a loose grey T-shirt and baggy navy pants.

Going makeup-free for the outing, Jackie looked worlds away from her usual glamorous on-air persona, instead favouring comfort as she padded along.

At one point, she lifted a hand to her forehead as she walked, appearing lost in thought, before later being spotted speaking quietly on her phone with her head lowered.

Her shoulders were slightly hunched and her pace unhurried.

Jackie gave the impression she was eager to avoid attention as she made her way through the street.

In another moment, Jackie spoke on her phone while keeping her head down.

It appeared to be a serious outing for the usually upbeat radio star, who looked worlds away from her bubbly on-air persona.

It comes after Kyle Sandilands dismissed reports his long-running radio program with Jackie has come to an end after he was absent from Thursday’s show.

Speaking on Friday’s broadcast of The Kyle & Jackie O Show, Kyle, 54, addressed headlines suggesting he had been pulled from the airwaves, insisting his absence was simply due to a sick day.

The presenter explained he had been up through the night caring for his unwell baby.

‘I haven’t vanished, everyone,’ Kyle said at the top of the show.

‘According to the newspapers, The Kyle & Jackie O Show was over, and I vanished. It just goes to show you can never believe what you read in any of the newspapers.

‘I feel they may have had their phones cut off; no one even rang to check.’

Kyle said his three-year-old son Otto had been coughing throughout the night.

‘It was a hard night [with the baby]; every time he coughed I sort of [woke up], then I had a headache,’ he said.

He added it was ‘hard enough’ to front the show on a good day, let alone after a night of ‘broken sleep’.

Kyle previously expressed his ‘regret’ over the fiery on-air clash that left co-host Jackie, in tears.

An emotional Jackie said she was deeply ‘offended’ by his brutal comments during the clash.

On Wednesday, Kyle admitted he wished he had handled things differently on The Kyle & Jackie O Show.

‘I obviously upset her. Maybe, in hindsight, I shouldn’t have said it on the air. But we say a lot of things on the air here,’ said Kyle.

‘It was never meant to hurt her feelings and obviously it did. I regret hurting her feelings. No one wants to hurt someone. Especially someone you care for.’

‘I don’t really know. The show is just ploughing ahead anyway. I’m just leaving this up to management,’ he added.

Kyle went on to say he just wanted to be back on the air with everyone happy, adding: ‘I want her to be happy and enjoy it. I also want the same thing.’

He then joked he didn’t care if any of the other producers or staff members were happy because he would ‘swap them all out in a heartbeat’ for Jackie.

Jackie was moved to tears after Kyle slammed her over an apparent ‘fixation’ with astrology.

The pair were discussing the latest developments regarding Andrew Mountbatten-Windsor, when Jackie proceeded to read out the disgraced royal’s birth chart.

Kyle then proceeded to lambast his co-star, claiming that her love for astrology was affecting her work.

When Jackie attempted to defend herself and accused him of launching an attack on her, he stated he was only expressing the ‘facts’.
