Kyle Sandilands has revealed the reason behind his bizarre feud with beloved biologist Sir David Attenborough.

On Monday's Kyle & Jackie O Show, the 53-year-old shock jock was reminiscing on some of his celebrity conflicts, when a caller brought up the British broadcaster, 98.

'David Attenborough was no fan of mine. But I liked him, great guy,' Kyle said of the award-winning natural historian.

'He was lovely,' co-host Jackie 'O' Henderson agreed. 

'But he didn't like us because we played animals having sex to him and he had to guess which animal it was,' Kyle added.

'One of them was two turtles rooting underwater and we played the noise, and then him and I had a big argument because he said "how has this been recorded underwater?"'

However, Jackie clarified the nature of the conflict, explaining: 'He was disputing they were turtles and you said "stop getting your knickers in a knot, they are." But then what did we find out five years later?'

'That the staff couldn't get turtles rooting so they just got two blokes in the studio...making the noises, so he was right,' Sandilands admitted.

'And I carried on. "You don't know, what would you know? You don't know everything."'

However, Kyle and Jackie said they have since found out their staff at the time had lied to them about the sound effects.

'Get him on now, I'll apologise,' Kyle joked, before the show moved on to other topics. 

Attenborough is a beloved advocate for the natural world, winning the hearts of the public throughout his career, which first started more than seven decades ago.

His award-winning nature documentaries such as the Planet Earth franchise have been wildly popular worldwide.

In 2022, he was named a 'Champion of the Earth' by the United Nations Environment Program due to 'his dedication to research, documentation, and advocacy for the protection of nature and its restoration.'
