The former couple, who married on Aug. 14, 2010, in a Santa Barbara, Calif., ceremony surrounded by 100 guests, have one son, Luca Cruz Comrie, who turns two in March.

Duff and Comrie welcomed their first child on Mar. 20, 2012. "We are overjoyed," the new mom tweeted at the time. "He is surrounded by so much love!! Mom and baby are both doing extremely well."

In June 2012, just three months after giving birth, Duff opened up to E! News about being a mom, gushing, "There's really no words to describe it. It's the most incredible thing every day. It softens you so much. I feel like a big mushy ball." She added of Comrie as a first-time father, "He's really incredible. He's so hands-on, so thoughtful, so loving. He's really a natural, it's incredible. I got really lucky."

At the time, Duff also talked about keeping the spark alive in the marriage with a newborn at home. "We go out like once a week together and try and do something fun," she said. "We either go to dinner...we're going to go bowling next week. It's weird scheduling so much because we used to do things on a whim and no we have to schedule. But it's good. It's really important for your relationship."
