Kyle and Jackie Os Inevitable Showdown Unfolds

once said she so relished working with 'best mate' that she did not consider what they did together a 'job'.

But the pair's 26-year on-air partnership, the most famed and well-paid in the Australian radio industry, crashed and burned on Tuesday, with Henderson's $100million contract terminated after she declared she could no longer work with the man she once called her closest friend. 

With KIIS FM's Kyle and Jackie O Show now in tatters, Henderson's future in radio is uncertain, while Sandilands has been benched amid what ARN has .  

The fallout between the duo was a long time in the making, with the cracks of a brewing feud showing for some time, and boiling over in recent months.

Tensions were visible last year, when Kyle's declaration that Jackie was 'off with the fairies' signalled his growing annoyance over his co-star's more esoteric interests.  

Sandilands' open vitriol as he slammed Henderson's 'airy fairy' proclivities was a sure sign that the relationship was disintegrating. 

The fiery exchange was captured in an unaired segment. 

In the recording, Sandilands, 54, is heard goading Henderson, 51, about being 'off with the fairies' and taking calls instead of working.

'There's a lot you don't remember. Are you sure that you're the full quid?' Sandilands began.

'I don't know if you are. Remember the other day when I said something about being on the phone and you said no I haven't? 

'We all laughed because nearly every break you were on the phone, but you genuinely thought that you weren't.' 

Henderson snapped back: 'That actually annoys me, that you did that, because I was on the phone - I was researching stuff to do with the segment that was coming up and I specifically remember that you guys were like, 'pay attention to do some work'.

'And I was like hang on a sec. I was actually doing work on the phone.'

The tit-for-tat continued before Henderson finally had enough. 

'Okay I'm going!' she raged.

'I'm constantly getting f***ing gaslit around here!' she added, storming off.

'Can't mention anything to you ever. Can you believe it?' Sandilands said as she left.  

The ill-will continued this year, when, just days before last month's 'astrology' bust up, Kyle angered his co-star as he belittled her recovery from addiction, which led to a 2022 rehab stay at the Betty Ford Clinic. 

Jackie lambasted Kyle for not reading her 2024 memoir, The Whole Truth, which detailed her battle with substance abuse. 

'If I was ever to read a book, I'd read your book,' Sandilands said, when Henderson admitted she did not watch him on Australian Idol, where he serves as a judge.

'Oh yeah, I don't need to feel bad about it either,' Henderson replied.

'What do you mean?' Sandilands pressed.

'Because you didn't read my book,' Henderson responded.

Newsreader Brooklyn Ross chimed in: 'Aren't you interested in, like, everything she did in rehab Kyle?'

'No. Is that in (the book)? What'd she do?' Sandilands said, before clapping.

'Clapping and being positive, I'm not into. I'm already happy. I don't need that. I don't need some old lady to tell me how to be happy,' Sandilands said, before clarifying that the 'old lady' referred to Betty Ford. 

'I'm soft now,' he added.  

'Really? Are you though? A leopard can't change its spots really, can he?' an irritated Henderson argued. 

Days later, tensions boiled over when Sandilands mocked Henderson for seeking out an astrological birth chart for Andrew Mountbatten-Windsor.

Henderson has been AWOL from the Kyle & Jackie O show since Friday, 20 February, after Sandilands .  

During the on-air feud, Henderson broke down in tears when the pair were discussing the disgraced royal.

Sandilands got angry at her when she proceeded to read out the royal's birth chart.

He lambasted his co-star, claiming that her love for astrology was affecting her work.

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

An emotional Henderson said she was deeply 'offended' by his brutal comments.

She then demanded a leave of absence following the altercation – never to return.  

But there was notable tension long before the straw that broke the camel's back. 

Henderson also stormed out of the studio in September last year after the duo clashed during an ad break.

Sandilands revealed the argument had sparked when Henderson accused him of not being interested in what she was discussing.

'Any relationship is not always smooth sailing. She cracked the s***s and left, but fear not, this show will not miss a beat,' he said.

It seems that leaving her popular KIIS breakfast show had been on Henderson's mind for a while. In July last year, she revealed plans to step away from the mic for good after her 10-year contract wraps up
