Kyle Sandilands has dramatically walked off his radio show as he revealed he "had to leave".
While hosting the Kyle & Jackie O Show on Thursday morning, the shock jock interrupted to announce he had to rush off as his fiancée was going into labour.
"Guys, I'm broadcasting from home for a reason, and that reason seems to have raised its head now," he said.
"I think I might have to leave the show ... and go to the hospital."
Jackie 'O' Henderson then excitedly asked, "Oh, it's time?".
Kyle sounded panicked as he prepared to leave and told everybody to calm down as they clapped and cheered.
He is then heard in the background saying, "Ok, right, are you ready? Let's go", before he says "I'm so sorry" to his co-host.
"I feel very unprepared ... I've got my bag ... yeah I've gotta run," he said before telling Jackie O he felt like he was "abandoning her".
"Kyle's having a baby," she said excitedly.
"I'm, like, freaking out, we weren't expecting it. We have no idea how long this is going to take."
Later in the show, Jackie O revealed the pair had given birth.
"Little Otto was born this morning. Mum and bub both doing well," a text message from Kyle said.
'Kyle's beyond excited. Kyle will be back on tomorrow's radio show to chat all things Otto," Jackie O added.
Kyle surprised listeners a year ago when he announced he and his partner were trying for a baby. He later announced the news they were expecting their first child together in February.
The 51-year-old and his partner then held a lavish gender reveal party on a yacht where two planes flew over Sydney Harbour released blue smoke to indicate it was a boy.
In May, Kyle asked Jackie O to be the godmother of his son, who he planned to name Otto, in an emotional moment.
The stunned radio host immediately clapped her hands over her mouth in surprise, and hugged both Kyle and his fiancée.
