Her admission comes a few weeks after Tammy and Emilee Hembrow revealed their older sister is expecting. Taking to their new podcast, Hanging With The Hembrows, mum-of-two Emilee teased the news, saying: "One of us here is pregnant right now, right this second."
"It's Amy," she and Tammy screamed before their older sis added, "It's me, I am so excited! It's now the size of a big lemon."
Amy confirmed she and her fiance Rory Carmody— who popped the question in June 2019 while holidaying in Japan— had been trying to conceive for a number of months, but didn't expect she'd fall pregnant so soon!
"We were trying and then we stopped and then it happened," she said, with Emilee adding that's not uncommon.
The happy news follows Tammy's shock announcement that she'd fired her pregnant sister Amy from working on her widely popular activewear brand, Saski Collection.
During a recent episode of their podcast, the close friend of Kylie Jenner said she sacked Amy— who served as the company's general manager— after they continuously butted heads over what was best for her brand.
"It was because we were sisters, she wouldn't really listen fully to what I'd say. Like, she'd think that she knows best," said Tammy, who launched the business in May 2017 and now has a large team of employees based on the Gold Coast.
Although Amy had been involved in the business from day dot, the fitness model said their constant arguing eventually took a toll on their personal relationship— with the star admitting her sister didn't talk to her for several days after she was let go.
"Now that [Amy] hasn't been working for me for a little while, it has actually made us get along so much better. I don't regret it."
"The truth is, I do feel like I know what's best for you. It's really good for me too, though. I always felt that Saski was Tammy's baby," Amy said, before admitting she's since started her own business with their other sister, Emillee.
