Kaley Cuoco Shares Cute Photos of Daughter Matilda in Trolls Halloween Costume but Without ‘Fun’ Pink Hair: ‘Oh Well’

Kaley Cuoco’s daughter is celebrating her first Halloween! 

On Saturday, Oct. 19, the Bang Bang Theory alum, 38, shared two snaps to her Instagram Stories of her 18-month-old daughter Matilda – whom she shares with fiancé Tom Pelphrey – getting into the Halloween spirit. 

"First widdle Halloween party invite," Cuoco wrote on a picture of her daughter in a colorful dress. "She was Poppy from Trolls but wouldn’t wear the headband with the fun troll hair LOL oh well."

Matilda rocked a dress with a white T-shirt decorated with two colorful characters from the popular animated Trolls movie franchise. The top also had a rainbow design with stars. The bottom of the outfit was made of colorful tulle with silver stars. 

The toddler wore matching hot pink tights and sparkly sneakers in the photo, which showed her playing with a pumpkin-shaped ball. 

In a second snap, Matilda is looking off into the distance, and her mom applied a GIF of Poppy on top of the photo.

Cuoco and Pelphrey welcomed their first child on March 30, 2023. The couple announced her birth on Instagram, calling her the "new light of our lives" alongside a set of family photos.

In September, the actress spoke with PEOPLE in an exclusive interview about how her daughter has a "fearless" nature and has “never been scared" of a little danger.

"She eats everything. She loves being outside. She loves her dad. She's kind of like a boy. She loves airplanes and monster trucks, helicopters. Anything in the sky she thinks is the most amazing thing," the proud mom gushed of her daughter. "And she loves horses, so that's great."

Cuoco is also a mom to numerous animals, including several dogs, whom she and Pelphrey spoil. 

The actress told PEOPLE in an exclusive interview in celebration of National Make a Dog’s Day on Oct. 22, "Our dogs are so spoiled, it's a total problem. Whenever anyone comes over, they say they want to come back in their next life as one of my dogs."

She added, "It's basically their house, we just live here."
