Levine and Prinsloo were married in 2014.
Levine and Prinsloo also have two daughters, named Gio Grace and Dusty Rose.
Levine and Prinsloo took a break to eat lunch, where the mother-to-be displayed her bump in the silky flower-adorned dress.
In a conversation with Entertainment Tonight in November, Prinsloo talked about the possibility of growing their four-person family.
In a adorable family picture, Levine was seen along with one of his daughters wearing a pink blush maxi-halter outfit.
Then, Prinsloo, is paired with their daughter in a frock that was off-shoulder with a tie-dye pattern from the same company.
