Moderator - Tomas Kauer 
Jackie 'O' Henderson will be stepping away from her KIIS FM Breakfast show after an on-air clash with longtime co-host, Kyle Sandilands.
On Monday morning's show, Sandilands confirmed his co-host would be taking a break for "a couple of days" to "gather her thoughts" after a discussion between the two on Friday became heated.

The presenter said he "spoke with" Henderson yesterday, but only via text message rather than on the phone.
Henderson is yet to publicly acknowledge the on-air argument or her absence from the show.
On the morning of February 20, Henderson and Sandilands got into a tense argument after Henderson took time out of a segment to read from Andrew Mountbatten-Windsor's astrology birth chart.
While the host seemed excited to share her findings, Sandilands quickly shut her down.

"Your fixation on this has made you almost unworkable," he told his co-host live on air.
"You are off with the fairies with this s--t, it's mental."
While Henderson said she was offended by her co-star's comments, he nevertheless continued to share his thoughts.
He said her fixation on astrology charts made her like a "drug addict", knowing Henderson has faced addiction struggles before.

He also claimed it had started to affect her work, going so far as to say she didn't know what was going on during some segments.
"You are not doing the rest of the job, and everyone in this building has mentioned it to me," Sandilands said.
"Everyone has said, 'What's going on with Jackie? She's off today.'"
"You don't know what the f--k is going on all the time, because you're looking at that phone, playing in the stars, and it's ridiculous," he added.
"You can enjoy that, but you can't take over your whole life."
Listeners could hear Henderson becoming emotional as she accused Sandilands of attacking her.
The pair have been friends for more than two decades, and have hosted a radio show together since 2004.
