Hilary Duff, Kristin Cavallari, Adele and more stars who were under 30 when they welcomed their first child
At the age of 25, the former Hills star welcomed her first child, son Camden, with fiance Jay Cutler on Aug. 8, 2012. "I was just surprised with myself about how natural it all came to me and how very at ease and calm I was with the whole thing," Cavallari told Us. "I'm still me -- I still enjoy the same things and like the same things. I'm just an older, more mature version of myself."
