Fans Can't Get Over Kaley Cuoco and Tom Pelphrey Switching Roles in 'Top Notch' Family Photo

Kaley Cuoco and Tom Pelphrey dressed up like their favorite people for Halloween this year—each other!

The Big Bang Theory alum took to Instagram on Thursday, Oct. 31, to share a carousel of pics revealing her family's Halloween costumes, and fans couldn't get enough of the clever disguises.

Cuoco, 38, wore a blue NFL jersey, fake beard and baseball cap in the first photo of the series (as fiancé Pelphrey is a fan of the team), holding her partner's monogrammed thermos in one hand. Pelphrey, 42, was dressed in a pink Nike hoodie, matching sweatpants and white slides, accessorizing with a long blonde wig, a pair of Cuoco's glasses and her checked phone case. Instead of a thermos, he held their pet dog in his right hand.

The pair's 19-month-old daughter Matilda stood in front of her parents wearing a fluffy white unicorn costume with rainbow wings and a matching horn.

"🎃 Happy Halloween from Tom, Kaley, and their little unicorn! 🎃 😆" Cuoco captioned her post.

Cuoco and Pelphrey started dating in 2022 and got engaged in August 2024, but the Flight Attendant actress told PEOPLE in September that they're in no hurry to walk down the aisle, admitting they "haven't started planning anything yet."
