"Ugh.... the skin, the blue eyes, the placement of the freckles, the best part of all is the placement of his heart," she shared. "My sweet sweet Luca. I love you all the way."

Earlier this week, the Younger actress celebrated her son's birthday with some delicious treats and epic family time. "Bday Cake makin going down," she shared on Instagram Stories.

Matthew also showed off the family fun on the 8-year-old's big day. "Making this dude's bday cake," the step-dad wrote on his Instagram Stories.

Last month, she documented her eccentric makeup look that was done by none other than her baby boy.

"I'm getting my makeup done by an 8-year-old," she told her followers. "It's subtle; it's unique. I've never done a makeup like this before, but I like it—especially the left upper part."

It's clear that Hilary and Luca have a special mother-son bond. Moreover, she's not to be messed with when it comes to her kids.
