Hilary Duff's Son Luca Kill Us With Cuteness in a Cookie Monster Beanie—See the Precious Pic

Twenty-five-year-old star and her hubby step out with their little one in Studio City, Calif.

We already know Luca Cruz Comrie and Hilary Duff are one adorable mother-son pair, but this pic takes the cake (or should we say cookie?). 

The former Disney star and hubby Mike Comrie stepped out in Studio City, Calif., Sunday for a morning breakfast bagel with their little one in tow, and the mother of one was snapped carrying her baby boy, who looked cute as a button in a Cookie Monster beanie. 

Talk about a seriously sweet snapshot. 

The 25-year-old star stayed true to her mother-son matching trend, sporting a colorful beanie, jeans, t-shirt and leopard print kicks for the casual outing. Her charming tot showed off his love of Sesame Street and kept warm in a yellow sweatshirt. 

Little Luca  is quickly approaching his very first birthday. He turns the big 0-1 on March 20. 

Can't wait to see how the whole family celebrates!
