"ROUND 2," the Victoria's Secret model wrote on Instagram, while wearing a bikini that showed off her stomach.
Prinsloo gave birth to her and Levine's daughter Dusty Rose on September 21, 2016. Ever since, the pair has gushed over their new baby.
"I have a daughter, I have the most beautiful wife in the entire world," Levine told the crowd. "I am one of the luckiest people who's ever lived and it has nothing to do with me. It has to do with the people who love me the most."
Prinsloo shared a photo of the whole family hanging out on the dad's new star, with a sweet message in the caption.
"A very surreal and amazing day for our family. I'm so proud of all your accomplishments, but mostly I'm proud of the amazing person you are. Best dad best husband, we love you," penned the model.
"I don't know anything, but it's kind of part of the beauty of it, honestly. There are a lot of instincts, a lot of things that kind of kick in and switch on. It's a beautiful experience."
