Adam Levine and Behati Prinsloo Welcome Daughter Geo Grace The couple announced the birth of their daughter, but didn't reveal the exact birth date. Geo Grace joins big sister, Dusty Rose, who is 17 months. Prinslo, 28, took to Instagram in September to announce that she and Levine, 38, were expecting a second child. Judging by past comments from Levine, this likely won' t be the couple's last child. I want a lot [of kids], I thrive in chaos. She was an only child, so she wants like 100 babies. I don't know if I can do that. That's a lot of babies.
