"It's only been a day, but 11 looks good on you, my boy. I know you will kick this year's butt! (Sorry for my day late … ☺️, you keep us all very busy) love you beyond how my brain and heart can compute 💞." Appearing on an episode of Dear Media's Good Guys podcast with Josh Peck and Ben Soffer earlier this month, Duff opened up about how she "always wanted to be a young parent." The Lizzie McGuire alum said she feels she "always knew" she was "meant to be a mom." It wasn't always an easy road, noting that at one point she "had a two-year-old and was divorced," which kept her from bonding with a lot of her peers. "It was hard cause I didn't have any friends that were having kids yet. But I just like figured it out and loved it. I love being a mom so much," she said. Noting that it "was young, for sure," Duff added, "I wouldn't change it at all."
