Kaley Cuoco's Boyfriend Karl Cook Reveals Her Hidden Talent!

Who knew Kaley Cuoco was so musical?

The 31-year-old actress – who recently agreed to take a pay cut to give raises to some of her Big Bang Theory co-stars – showed off her tambourine-playing skills on stage at the BNP Paribas Open, an international tennis tournament held in Indian Wells, Calif., this month.

“You know part of a relationship is you learn more and more about one another,” Kaley‘s boyfriend and fellow equestrian Karl Cook captioned the Instagram video below. “Today I learn Kaley can play the tambourine. You should have seen my surprise, what’s next honey, falconry. Ok actually please falconry, that would be awesome!”

The staff apparently had to use photos from the Internet to print on Kaley and Karl‘s ID cards!

“@bnpparibasopen where they found pictures on the internet for our credentials,” Karl shared. “I’m not at all sure where they got my picture but I feel like they intentionally found a horrendous picture to accentuate the juxtaposition. I mean come on. Kaley looks like a goddess and I look some one who was just peeled off the pavement after tailgating too hard at a NASCAR race.”

Pictured: Kaley grabbing some grub after her yoga class on Monday (March 13) in Studio City, Calif., and going grocery shopping with Karl at Whole Foods in Los Angeles that same day.
