Bowie is Holliday’s second child, and will be little brother to 10-year-old Rylee, Holliday’s son from a previous marriage.

Speaking to People, the model said she expects some big changes second time round.

“It’s been 10 years since I had a kid, so there are so many things that are new,” she said.

“My friends that have babies are posting all of these new swings and breastfeeding techniques and new bottles, and it’s really overwhelming because I thought, ‘I’ve already done all this,’ but it feels like I haven’t. I’m having to relearn a lot!”

Holliday’s pregnancy has attracted a great deal of media attention in recent months, with many people on social media claiming that her size is unhealthy and may be harming her unborn child.
