The 28-year-old model shared a sweet moment with the 39-year-old singer and "The Voice" coach on Sunday during their trip to Coachella music festival.
Prinsloo posted a picture of herself smiling and embracing Levine as she sat on a countertop. The mom-of-two wore leopard-print pants with a cropped tee, bucket hat and mini backpack.
"Baby boiii," she captioned the snapshot.
Prinsloo, who welcomed daughter Gio Grace in February, had showed off her slim post-baby figure in a photo the day prior. The picture, which she captioned with a cherry emoji, shows her striking a pose against a railing.
Prinsloo shares Gio Grace and 18-month-old daughter Dusty Rose with Levine. Levine said prior to Gio's birth that he hopes to have several children.
"I want a lot," the singer said on "The Ellen DeGeneres Show." "I thrive in chaos. I genuinely enjoy it. We love it."
"[Behati] was an only child," he added. "She wants, like, 100 babies, but I don't know if I could do that."
