Adam Levine's bae Behati is bumpin' with another baby!

Looks like we're about to have another little Levine running around!

Adam Levine's supermodel wife, Behati Prinsloo, revealed a burgeoning baby bump on Instagram on Wednesday, to reveal she and her Maroon 5 crooner husband are expecting their second child.

"ROUND 2," the 28-year-old Victoria's Secret model captioned the mirror pic of her debuting the bump in a two-piece undergarment.

ET has reached out to Levine's rep for comment.

A source tells ET Adam has always talked about wanting a big family. “He and Behati want lots of kids, and they want them close in age.," the source says. "Adam is over the moon, as is Behati. They are in love with Dusty and can't wait to make her a big sister."

"Adam has already been making sure his schedule next year has time to allow for him to take off work and be with the new baby,” the source adds.

Looks like Dusty Rose isn't going to be the baby anymore! The superstar couple's daughter was born on Sept. 21, 2016.

Congrats to the happy family!
