Adam Levine and Behati Prinsloo are growing their family!

The Maroon 5 frontman, 43, and Victoria's Secret model are expecting their third baby.

The couple's new arrival will join daughters Gio Grace, 4, and Dusty Rose, 5.

Levine and Prinsloo stepped out in Santa Barbara, where mom-to-be showed off her baby bump.

Prinsloo talked about the possibility of expanding their family of four.

"We always knew we wanted a second one."

"I do also want five kids, but don't even think about it," she explained to the outlet.

"You know what, never say never. We want a big family, who knows?" Prinsloo told.

"We're leaving it up to fate and just what happens. What will happen, will happen. So there's no limits to it."
