"ROUND 2...." wrote Prinsloo, 28, alongside a photo of herself in a bikini, showing off her growing baby bump.
Speaking of her and Behati again at a Hollywood Walk of Fame event, he said: "I have a daughter, I have the most attractive wife in the entire world".
Though the first-time parents get "little sleep", Prinsloo said, "It's always worth it when you see her face smiling back at you".
"She's unbelievable", Levine told Ellen DeGeneres. "It has to do with the people who love me the most, and so I thank all of those people", said the singer.
