Kaley Cuoco & 'Big Bang' Cast Perform Flash Mob on Set!

Kaley Cuoco wears a towel around her waist while walking to her car after a yoga class on Monday afternoon (December 15) in Los Angeles.

A few days earlier, the 29-year-old actress was spotted carrying her yoga mat to her car after yet another workout session.

Kaley and her Big Bang Theory co-stars recently put on their annual flash mob. We can’t wait to see the video!

“Yep that’s right.. @bigbangtheory_cbs cast and crew put on, yet again, another epic, hilarious, badass, incredible surprise dance extravaganza at the end of tonight’s taping,” Kaley captioned an Instagram photo. “Choreographed by @bricuoco and her team, we nailed it!!! Might have been one of the best nights ever….(pretty sure this will hit that thing called the Internet pretty soon) 😂 #whenindoubtdance #flashmob #bbt”

FYI: Kaley is wearing Tkees flip flops with her plaid outfit and Peepers sunglasses.
