Kyle Sandilands reveals his very surprising sexy underpants

Things got wild in the Kyle & Jackie O studios on Thursday.

Kyle Sandilands, 51, made quite an impression on his guest hosts on the radio show, dropping his trousers while live on radio.

‘Show us your undies Kyle,’ KIIS FM producer Pedro Cuccovillo Vitola said to the host.

‘Yeah, get up and show us,’ Executive producer Sonia Jahshan added. ‘Give us a flash.’

Kyle sighed, muttering ‘for God’s sake’, before proceeding to stand up and pull part of his pants down to reveal a nice set of black Tommy Hilfiger underwear.

The studio erupted into cheers for the radio giant, who’s just welcomed his first child.

‘Actually, they do look good on you Kyle!’ Sonia exclaimed.

‘Look how good your butt is!’

Kyle began to shake his hips in an attempt to twerk in front of the microphone, with his pants still half down.

Kyle and his fiancée Tegan Kynaston welcomed their first child together, son Otto, last Thursday.

In a heartwarming Instagram post on Tuesday, the Kyle and Jackie O Show’s official Instagram page reposted a photo of the radio shock jock bonding with his adorable baby boy.

In the image, Kyle can be seen tenderly holding his little bundle of joy, who was wrapped up in a colourful blanket.

‘Kyle and baby Otto. Isn’t this just the cutest?’ the radio station captioned the post.

The photo was taken by their midwife Vicki, who also posed for a selfie with the radio titan on her own social media page.

His co-host Jackie O announced the happy news on-air and Kyle’s manager Bruno Bouchet told Daily Mail Australia: ‘Little Otto was born this morning. Mum and bub both doing well.’

Jackie, who is Otto’s godmother, shed tears of joy as she declared: ‘Otto has been born!’

Kyle later gave a rather graphic update about the birth, telling ‘Intern’ Peter Deppeler live in the hospital car park: ‘Otto’s born, Otto’s fabulous. I cut the cord, I didn’t realise it was like tough calamari and blood spurted out.’

On Monday, Kyle said on The Kyle and Jackie O show he can’t stop ‘staring and smiling’ at his newborn son.

‘Are you in that love bubble?’ co-host Jackie O Henderson asked.

‘100 per cent. We just keep looking at him and then we look at each other and smile and one of us has a little tear roll down,’ Kyle admitted.
