She's a knockout! Meet Jeff Horn's baby girl Isabelle
WORLD champion boxer Jeff Horn may have finally met his match in the form of his tiny 3.58kg baby girl.
Just the mention of seeing newborn Isabelle Kate come into the world is enough to bring a tear to the formidable fighter's eyes.
After 18 hours in labour, Jo Horn gave birth to the healthy baby girl at 7.40pm on Saturday, capping off a stellar year for the couple and one they say will be almost impossible to beat.
An exhausted but overjoyed Jo said her husband had taken to fatherhood like a duck to water.
"I'm really surprised what a natural he is with her," Mrs Horn said.
"I always thought I'd be the more hands on one with her but he's been so wonderful and he might even teach me a thing or two."
Mrs Horn, said the pair were "on cloud nine" and couldn't wait to get baby Isabelle home.
"She's just perfect and we can't stop staring at her and thinking oh my gosh we created this," she said.
In 2017, Horn became the world welterweight boxing champion of the world, successfully defended the title and won a slew of awards.
But he says none of it compares to welcoming his first child.
"It's number one for sure," he said.
"Nothing really compares to that, you can't beat this moment."
Horn said it was "frustrating" seeing his wife in pain and not being able to help.
"It was extremely frightening and I just wanted them to be all right," he said.
"Not being able to do anything was so hard."
It was quite the role reversal for the Brisbane couple.
"He now knows what I go through every time I watch him in the ring," Mrs Horn said.
Horn said baby Isabelle had her mum's hair but had inherited his ears with one having a slight kink in the top, just like his.
"She's gorgeous," he said.
"I had tears in my eyes and even just before talking about it makes me start tearing up.
"It was hard to grasp the situation and I was just so excited and so happy and relieved that she was out safe and in my arms."
After Jo went into labour about 3am Saturday, the calm couple had breakfast, ducked to the post office and then went to hospital about 7am with Isabelle arriving about 12 hours later.
"Isabelle is great and she's been pretty well behaved and hasn't been crying too much," Horn said.
"We're waiting for the night she keeps us up all night but we've been able to get a few hours in at least for now."
Horn said he was enjoying a break from his gruelling training schedule.
"I'll at least have another couple of weeks off training and I might start back very light and probably won't go back to the boxing gym until the start of February," he said.
"I guess now she's come it makes 2017 a very hard year to beat with that world title and successful defence and then right at the end the cherry on top is the baby.
"We couldn't have imagined this time last year that all this would happen."
