“In the last week of filming, Audrey had contractions seven minutes apart, so it was going to happen at any moment,” Osher said.
“I was getting nervous while hanging around the mansion and my executive producer … took one look at me and said, ‘Osh, you can’t miss this. It will be the best day of your life, don’t worry we will make it happen.’
The TV presenter went on to say that the production crew rallied together to ensure that the finale episode could work in his absence and he didn’t miss his son Wolfgang’s birth.
“It was odd not to be there. It is the moment they go off into the wild and I really like to give them a hug and tell them I am happy for them. But I am sure I will catch up with everyone once the outcome is out there,” he said.
Following the news of Wolfgang’s birth, Osher previously took to Instagram to share a sweet black and white snap of himself with his son.
"Please meet Georgia’s youngest brother, Wolfgang. We call him Wolfie for short," Osher began.
"He and @Audreygriffen did so well on Friday when he was born perfectly formed with ten fingers and toes, healthy and happy at 3.97kg. (Though between the delivery bed and the scale he did do a massive poop - and the doc agreed that if he hadn’t he would have topped 4kg easily.)"
Osher continued his lengthy Instagram post by praising his wife: "I am in complete awe of my wife. What I witnessed her do, the power I saw her summon from within her to bring this boy into the world was utterly astonishing."
The Bachelorette finale will air on Thursday night.
