Hilary Duff's Little Boy Is Getting So Big!

Hilary Duff and her son Luca were spotted out and about in Los Angeles on Thursday, and the former Disney star and hubby Mike Comrie will be heading down to Newport Beach over the next few days to celebrate Christmas with her family.

“It’s nine kids going crazy, basically wrapping paper flying in the air, toys everywhere and mayhem,” she told Access Hollywood. “We’re really looking forward to that — we get to bring a baby this year! — so it’s really exciting.”

So how is her 9-month-old son faring with all the the holiday decor? “He’s into everything," she says. "I’m running around the house just trying to keep up with him. He’s so fast! He loves the Christmas tree. Obviously we have a funny looking Christmas tree [because] all the ornaments are at the top.”

So will Hil and her hubby be expanding their family anytime soon? “Mike and I are literally obsessed with Luca. We’re like, ‘He’s perfect. We should just be one and done," she says. "But I think once your baby starts getting older you miss that phase and you go in for round two. Maybe when [Luca's] two or three?”
