The 32-year-old model posted unseen photos with Levine, 41, and their two daughters, Dusty Rose, 4, and Gio Grace, 2, Sunday on Instagram Stories.
Prinsloo took "Post a picture of..." requests from fans while her kids were sleeping. When asked to share her favorite picture from her wedding, Prinsloo shared a photo of herself and Levine smiling and looking into each other's eyes.
Another fan asked Prinsloo to post the first photo of her and Levine together. Prinsloo shared a picture from 2012 that shows her and Levine goofing off and sticking out their tongues.
"Not first but close to," she captioned the post.
Prinsloo was also asked to share a photo of her unseen pregnancy belly. She posted a photo of herself in a bubble bath while pregnant with Dusty.
When asked to share a picture of a moment when she felt happiest, Prinsloo posted a photo of Levine and their two daughters.
In October 2019, Levine said on The Ellen DeGeneres Show that he's been a stay-at-home dad since his departure from The Voice.
"I'm obsessed with them," he said of his daughters. "I mean, I know that's a good thing 'cause they're my children. That's why I don't do much -- I genuinely just adore them in a way that I never knew I could adore any little person."
Prinsloo is known for her modeling work with Victoria's Secret, while Levine is the frontman for the band Maroon 5.
