Prinsloo revealed that she and Levine were expecting their second child last month, with a bump-filled bikini pic, while a source told ET that Levine has always talked about wanting a big family.
"He and Behati want lots of kids, and they want them close in age.," the source said of the couple, who are already parents to 1-year-old daughter Dusty Rose. "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 added.
