Seems Kaley Cuoco and her rumoured beau Karl Cook are set to up their romance rumours budding all around, like their latest adorable selfie shows. 'The Big Bang Theory' actress posted a throwback Thursday shot of her snuggled up to the 26-year-old equestrian on an unspecified beach.

"We absolutely mastered the ways of the selfie stick," the 30-year-old star joked in the caption for the loved-up photos.

The top image in the collage shows the duo looking out onto the ocean while the second, on the bottom, features Karl kissing Kaley's forehead as she smiles into the camera.

Less than a week ago, the two sparked initial dating rumours after the actress shared an image of the two during what appeared to be a hunting trip.
