Kaley Cuoco Turns Heads with Striking New Hair Color at U.S. Open

The "8 Simple Rules" alum stepped out at the sporting event with her fiancé last week, showing off a bold new hair color. The couple, who share a two-year-old daughter, have been engaged for over a year.

Kaley Cuoco attended Day 13 of the 2025 U.S. Open Tennis Championships on Friday, September 5. The longtime actress was joined by her fiancé, "Love & Death" star Tom Pelphrey, at the event, currently being held at the USTA Billie Jean King National Tennis Center.

Pelphrey kept it casual with a crisp white crewneck T-shirt layered under a camel-brown suede jacket, paired with loose, pleated beige trousers and dark brown leather shoes. Black aviator sunglasses and neatly groomed hair completed his polished yet laid-back style.

Cuoco opted for a playful, preppy-inspired ensemble with a white button-down shirt layered under a cream cable-knit sweater vest detailed with burgundy stripes at the neckline. She paired the look with a plaid pleated midi skirt, gray socks, and polished black loafers.

The TV star accessorized with gold hoop earrings, layered bracelets, and a soft beige clutch. Her hair was styled in two sleek, twisted space buns, and featured a noticeably darker brunette balayage with dirty blonde tips.

The "Big Bang Theory" alum, known for her signature blonde locks, first began experimenting with darker shades in late 2022. This latest transformation is her deepest brunette yet.

Prior to attending the U.S. Open on Friday, Cuoco supported her partner at the debut of his new miniseries, "Task," in which he stars alongside Mark Ruffalo and Emilia Jones.

The couple — who have been together for three years and share a two-year-old daughter, Matilda — announced their engagement in August 2024.
