Kaley Cuoco and Husband Tom Pelphrey Hilariously Dress as Each Other for Family Halloween Costume with Daughter Matilda

The couple celebrated the spooky holiday with their 19-month-old daughter

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

On Thursday, Oct. 31, the Big Bang Theory alum, 38, shared a carousel of photos on her Instagram as she celebrated Halloween with Pelphrey, 42, and their 19-month-old daughter. Cuoco and Pelphrey hilariously dressed as each other, with the actress donning a blue NFL jersey, fake beard and baseball cap.

Pelphrey wore Nike sweats, a pink Nike sweatshirt and white slides, wearing a blonde wig and glasses. Their daughter Matilda stood in front of them, wearing a rainbow unicorn costume. "🎃 Happy Halloween from Tom, Kaley, and their little unicorn! 🎃 😆," Cuoco wrote in her caption.

Earlier this week ahead of the spooky holiday, Cuoco posted photos on her Instagram Stories of Matilda in another adorable Halloween costume.

The first snap showed a close-up of the toddler standing in what appeared to be a playroom while wearing an adorable black-and-white striped prisoner one-piece outfit that had "Cutie Convict 0011" written across the chest. Matilda even wore a matching striped prisoner hat, as well as white shoes, to complete her look.

"Another Halloween lewk," the actress wrote across the bottom of the photo.

Cuoco's second photo was a black-and-white shot of her daughter in the same outfit, but this time outside. Matilda's mom had added an orange "Halloween" sticker over the image.

For Halloween last year, Cuoco went all out, dressing Matilda in five different costumes. Matilda clutched a purse and wore pearls in an "old lady" costume and smiled in a fuzzy bee onesie.

Cuoco captioned the adorable post explaining each costume: "1) Tildy the old lady 2) Who ya gonna call? Ghostbusters! 3) winner winner 🐔 dinner! 4) the cutest 🐝 5) our own personal 🏈."
