Levine had earlier posted a hilarious picture of Prinsloo and The Voice coach Blake Shelton, where the duo can be seen exposing their bellies. "Met these two sweet pregnant ladies today. Good luck@blakeshelton and @behatiprinsloo!" he captioned the image.

Prinsloo's pregnancy news first broke in March and since then The Voice judge has made appearances on various chat shows to gush about his wife and bundle of joy they are expecting.

"Watermelon, that's the thing in our house. A lot - so much watermelon. Maybe she just, like, really likes watermelon. I mean, it's delicious. I'm glad it's not, like, pickles or some weird thing," Levine said about the cravings of the mother-to-be.
