Adam Levine is expecting his first child with his wife Behati Prinsloo.

Levine used Instagram to post a topless pregnancy picture of Prinsloo to express his affection for his wife. The caption of the photo read “YOWZA” and was surrounded by flame emojis.

This post served as the latest in a line of appreciative posts directed to the future mother of his child. Levine began documenting their journey into parenthood on social media with a post of Prinsloo lounging in the sun with the caption, “My two favorite laker fans.”

In a later post 20 weeks into the pregnancy, Levine poses for a selfie with Prinsloo and jokes that his own baby bump is starting to show.

A similar joke was made with his co-star and judge of The Voice Blake Shelton. Sitting next to Prinsloo, both holding the curvature of their stomach the photo was captioned: “Met these two sweet pregnant ladies today.” Levine then tagged Shelton and his wife.

Met these two sweet pregnant ladies today. Good luck @blakeshelton and @behatiprinsloo!
