However, one entertainment insider has claimed there is still a 'very dark cloud' hanging over the long-standing duo.

Speaking on 3AW on Monday morning, entertainment journalist Peter Ford claimed that Henderson may not return.

'In fact, a couple of people have said to me if it was a horse race, I wouldn't be backing them for a win.

'It's a $200 million contract that could very likely be ripped up and binned. I'm told more than likely she won't be coming back ever.'

'There was a conference call that took place on Friday between Jackie O's manager Gemma and radio executives,' he said.

However, Ford claimed the meeting took a different turn.

Ford also mentioned the fact that during his tirade Sandilands claimed that KIIS staff had reportedly raised Henderson's 'lack of focus' with him personally, which he claimed 'really upset her.'
