The Biggest Loser trainer welcomed baby boy Arnold just under two weeks ago, and now she has revealed she "didn't even notice" she was in labour.
Speaking to Kidspot, the new mum, whose husband is comedian Ed Kavalee, said the arrival of baby Arnold was swift.
"We got to our weekly appointment and my obstetrician said, 'Oh, you're 2cm dilated, you're in labour!' And I said 'Oh, am I?' I didn't even notice. And then it was all happening from there, within two hours I had Arnold."
Tiffany went on to explain that their baby boy's arrival was complicated by the fact that his heart rate dropped prior to birth, and he had the umbilical cord wrapped around his neck. This meant that although his arrival was swift, it was incredibly painful.
"So I didn't have any time to enjoy the epidural, they pretty much flung me back, my legs went up in the stirrups and I had to start pushing," Tiffany told the publication.
When talking about the contractions, Hall reveals they were "off the scale" in regards to pain.
"I did not expect it to be so painful. I've done a lot of painful things in my life training wise and pushing myself but nothing can ever compare to that," she said.
Hall was recently praised on social media for her realistic and genuine response to 'bouncing back' into shape after birth.
She captioned the pic: ' Hey Arnold, this is a selfie. I am so proud of my body creating this beautiful baby boy. Arnold, my tiny knitwear model, what a joy you are.'
