Hilary Duff’s Son Luca Is All Grown Up as He Celebrates 10th Birthday

Hilary—also mom to 11-month-old Mae and 3-year-old Banks with husband Matthew Koma—also found time for joy, sharing pictures from Luca’s birthday celebration to her Instagram Stories. 
 
In one photo, the pre-teen was pictured standing in front of his cake, which was made out of a tower of chocolate brownies. Another image showed the family of five posed near an arcade game.
