Swanepoel, who celebrated her baby shower last month (and seemed to reveal her son's name will be Anacã), is clearly loving the pregnant life. On Sunday, the Victoria’s Secret model showed off her bump by a Buddha statue.
"My mood all day everyday. #ohhhmmm #8monthspregnant," she wrote alongside the pic.
Swanepoel isn't the only model enjoying the last stretch of her pregnancy. Pal Behati Prinsloo is so close to her Sept. 20 due date that her husband, Adam Levine, has rescheduled his upcoming tour dates with Maroon 5.
"Even when you think you've planned everything perfectly, sometimes life just kinda happens," Levine said in a statement. "Soon Behati and I will be celebrating the birth of our first child and, as I'm sure you all understand, I need to be there. I'm really looking forward to seeing everyone in the spring."
