Her son Luca was a lil' fireman, and it was ADORABLE!!!
The two were spotted in Burbank on Thursday where they passed out delicious candies to Trick or Treaters!
The mother-son duo were at Duff's parents house in Toluca Lake which we hear was one of the hottest spots for passing by families!
Aww! That's our Hilary! Always thinking of others while staying cute!
Can she be any more perfect???
