"There's really no words to describe it," Duff told us of motherhood at Bing and DoSomething.org's kickoff event for Bing Summer of Doing in L.A. "It's the most incredible thing every day. It softens you so much. I feel like a big mushy ball."
But is little Luca keeping Duff and her hockey-star hubby Mike Comrie from enjoying married life?
"We go out like once a week together and try and do something fun," the 24-year-old 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."
As for how Comrie, 31, is as a dad, Duff gushed, "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."
Duff says they won't be having any more little ones any time soon. "Obviously we want more kids but we want to really enjoy Luca. I'm young. I still want to work and I feel like I have a lot to do."
Speaking of work, Duff is jumping back in the music studio. "I'm getting kind of nervous," she dished. "Next week I have all these meetings set with different producers and writers. I'm excited to start that process and I'm so nervous."
