The author and media personality told in August that she won’t be rushing back to the gym soon after giving birth.

“There’s a lot of effort that goes in to the bounce back,” Hall told the publication.

“Hours at the gym and calorie restrictions. I’m not up for sacrificing time with my new baby to be pumping it out at the gym.

“My body has changed, and that’s all right. I have put on weight, but it’s beautiful, glorious weight.”

Hall and Kavalee, who stars on Channel 10’s Have You Been Paying Attention?, have been married since 2014.
