Kaley Cuoco Kisses Karl Cook After Horseback Riding-Filled Weekend

Kaley Cuoco and Karl Cook got loved up on her horseback riding trip!
On Thursday, The Big Bang Theory star shared that she was on "vacation" by posting a photo of herself in riding gear on Instagram, and it's been nothing but horseback rides and romantic moments ever since!

Cuoco and Cook were caught kissing while getting gas in West Lake, California, on Sunday, marking the first time we've seen them smooch in public.

Aside from the fuel up, most of the weekend has been filled with horses, as Cook accompanied Cuoco and her dog, Norman Cook, to the Flintridge Riding Club in La Cañada Flintridge, California, on Saturday, where the actress was competing in the 95th Annual Flintridge Horse Show.

Cook, a professional equestrian, didn't participate in the show, but an eyewitness tells ET that he gave Cuoco a good luck kiss before the competition began.

The 30-year-old actress didn't show off any of her own snaps with Cook, but she did post a gorgeous shot of herself posing with a horse named Bella underneath a rainbow. "Last night in the GP warm up ring with #bella #belly ... Had a beautiful rainbow looking down on us!#amidreaming (thank u Michelle for this awesome pic!) #nofilter," she wrote on Instagram.

The avid equestrian lover also shared video from her ride with another horse named Poker Face on Friday.

Even though Cuoco and Cook have yet to officially confirm their relationship status, Sunday's kiss seems to do just that, as did the PDA photo shared by the California native earlier this month.
