Kaley Cuoco Emmy: Actress Walks Red Carpet with Boyfriend Ryan Sweeting (PHOTO)

"The Big Bang Theory" star Kaley Cuoco showed off her new boyfriend at the 65th annual Television of Arts and Science Emmy Awards on Sunday.

The actress walked the red carpet with tennis player Ryan Sweeting.

"#emmyweekend greatest date ever ryansweething," the 27-year-old actress shared several photos of the two of them on Instagram.

The special evening marked the first big awards show for the pair, who kept close throughout the night especially on the red carpet.

The actress reportedly stumbled in her heels before heading in to take her seat, and had to be caught by Sweeting, an eyewitness told Us Weekly.

Sweeting, 26, and Cuoco were first rumored to be dating in August when he joined her at a horse ranch in Moorpark, Calif. The relationship came after her short-lived relationship with Henry Cavill came to an end.

Cuoco plays Penny on the CBS hit and was nominated for Outstanding Comedy Series at the 2013 Emmy Awards.
