Hilary Duff's mom knows her granddaughter Banks too well!

Over the weekend, the Younger star's daughter Banks Violet celebrated her fourth birthday with a celebration at home, where she received the "best present" from her grandma: a Harry Styles pillow.

In a photo on Duff's Instagram Story, Banks is engrossed in her gift, playing with the sequin pillow that turns from a solid color to a photo of Styles with the brush of a hand. "My mother wins best Present!" Duff wrote.

Other pictures from the party show Banks posing in front of her balloons in a birthday crown as well as a picture of Matthew Koma, whom Duff deemed a "hot dad," bringing out a pink two-tiered birthday cake.

Duff, 35, later noted that she and Banks had two parties in one day as she shared a mirror selfie of her and Banks, who changed her outfit into a unicorn Halloween costume.
