“Big Bang Theory” star Kaley Cuoco and her boyfriend Karl Cook looked happy and in love as they made their red carpet debut earlier this week.

The 30-year-old actress and her equestrian beau share a passion for horses and horseback riding, so it’s no surprise that they made their first red carpet appearance as a couple at the Longines Masters Los Angeles Gala in Long Beach, Calif., on Thursday, Sept. 29, Entertainment Tonight reported. The adorable couple was all smiles as they held hands and posed for photos.

For the event, Cuoco stunned in a colorful, floor-length wrap dress. Her gown complemented Cook’s equally eye-catching ensemble which consisted of a pale gray suit and blue hat. Check out Cuoco and Cook’s red carpet photos here!

Before heading to the event, Cuoco shared a close-up photo of her look for the night on her Instagram. In the photo, the actress appeared to be shocked as she got a close look at her hair and makeup after her pals were finished styling her. “Shocked that my girls actually did an OK job tonight,” she jokingly captioned the snapshot.

Earlier this year, Cuoco revealed that she and Cook bonded over their mutual love of horses. “ He's special. I think that the horse connection is special. Yeah, he's special,” she told ET back in June.

In fact, Cuoco — who was previously married to tennis player Ryan Sweeting — met Cook at an event related to their favorite animal. “We met at a horse show. I finally found my horse guy. I know. It was meant to be. He's an amazing, amazing rider. Rider and jumper. Amazing equestrian and great human. We share obviously our passion for horses and dogs and all that. And it's been lovely. So great,” she gushed about her boyfriend during a guest appearance on “The Talk” earlier this month (via E! News).

Catch Cuoco when “The Big Bang Theory” Season 10 airs every Monday at 8 p.m. ET on CBS.
