Hilary Duff's 4-Year-Old Daughter Gifts Her Hilarious NSFW Birthday Card: 'She Can't Read Yet'

Hilary Duff's daughter gave the singer a birthday card she'll never forget.

Duff's husband Matthew Koma shared a hilarious photo on his Instagram Story of the birthday card the couple's daughter Banks, 4, picked out for the actress, 35. The card featured a white birthday cake with rainbow sprinkles that read "Happy Birthday Dickhead" in red icing.

"Banks picked this out by herself for @hilaryduff. She can't read yet," Koma wrote across the picture.

Duff shares her two daughters — Mae, 2, and Banks — with husband Matthew Koma. She is also mom to son Luca, 11, whom she shares with ex-husband Mike Comrie.

In August, the star shared that her daughter Mae was sick and had to stay home while Duff and her other two kids enjoyed some time playing in a lake.

In one photo posted to her Instagram Story, Mae was wrapped in a blanket and looked with wide eyes into the camera. "Had to leave this sicky bean at home with an ear infection and fever 😞 😢," Duff wrote across the photo.

"But some individual time is so nice as well," she later wrote across a sweet selfie of her and son Luca.

Appearing on an episode of Dear Media's Good Guys podcast with Josh Peck and Ben Soffer in March, Duff opened up about how she "always wanted to be a young parent."

"It was hard cause I didn't have any friends that were having kids yet. But I just like figured it out and loved it. I love being a mom so much," she said.

Noting that it "was young, for sure," Duff added, "I wouldn't change it at all."
