Bienvenido a Mexico!

Kaley Cuoco showed off her teeny waist and toned stomach in a picture posted on Instagram on July 3 from Cabo San Lucas, Mexico. "Vaca!!! #cabocabocabo" the Big Bang Theory star captioned the image of herself with husband Ryan Sweeting.

Cuoco, 28, sports a cobalt blue ruffled bikini top with striped bottoms underneath jean shorts. A fedora hat covers her pixie cut.

On Wednesday, July 2, Cuoco shared a sweet moment captured on the beach. In the image, she and Sweeting are kissing and holding hands, with the caption (and nod to Friends), "Im his lobster."

However, the getaway isn't just couple time. Cuoco also posted a picture with sister Briana Cuoco and girlfriends including Ali Fedotowsky and Amy Davidson. "Girls just wanna have fun!" she wrote.
