Kaley Cuoco and her husband Tom Pelphrey wore an epic Halloween costume this year, and their daughter Matilda was along for the ride.

On Thursday, October 31st, The Big Bang Theory The 38-year-old alum shared a carousel of photos on her Instagram as she celebrated Halloween with Pelphrey, 42, and their 19-month-old daughter. Cuoco and Pelphrey had fun dressing up as each other, with the actress wearing a blue NFL jersey, a fake beard and a baseball cap.

Pelphrey wore Nike sweatpants, a pink Nike sweatshirt and white flip-flops, a blond wig and glasses. Standing in front of them was their daughter Matilda, dressed as a rainbow unicorn. “🎃Happy Halloween from Tom, Kaylee and their little unicorn! 🎃 😆,” Cuoco wrote in the caption.

Earlier this week, ahead of the spooky holiday, Cuoco took to her Instagram Stories to post photos of Matilda wearing yet another adorable Halloween costume.

The first photo showed a close-up of the baby standing in a playroom wearing an adorable black and white striped prisoner onesie with “Cute Prisoner 0011” written across the chest. Matilda even wore a matching striped prisoner hat and white shoes to complete her look.

“Another Halloween joke,” the actress wrote at the bottom of the photo.

Cuoco’s second photo was a black-and-white shot of her daughter wearing the same outfit, but this time outside. Matilda’s mom placed an orange sticker over the image that said “Halloween.”

For Halloween last year, Cuoco went all out by dressing Matilda in five different costumes. Matilda clutched her purse, wore pearls in her “old lady” costume and smiled in a fluffy bee onesie.

Cuoco captioned the adorable post explaining each costume: “1) Old Lady Tildy 2) Who you gonna call? Ghostbusters! 3) winner winner 🐔 dinner! 4) the cutest 🐝 5) our personal 🏈.”
