Hey, baby!

Supermodel mama-to-be Behati Prinsloo shared a new photo of her growing baby bump on Instagram on May 21, revealing her 22-weeks-pregnant bikini body.

Behati, 27 -- who's expecting a baby girl with husband Adam Levine early this fall -- captioned the pic with a simple hatching-chick emoticon.

The Victoria's Secret model wore a coral and pink bikini in the mirror selfie, which appears to have been taken in a bathroom.

Adam, 37, has been prepping for fatherhood with some social media humor lately.

In early May, he shared a pic of himself puffing out his stomach to match his wife's burgeoning belly, captioning that mirror pic, "Week 20 and I'm finally popping! #impregnanttoo."

On May 21, Adam's friend and "The Voice" co-star Blake Shelton followed suit, sticking out his gut to rival Behati's bump. "Met these two sweet pregnant ladies today. Good luck @blakeshelton and@behatiprinsloo!" Adam captioned that LOL pic.

Behati's latest photo comes two months after the news broke that she and Adam were expecting.
