‘Big Bang Theory’ Star Kaley Cuoco Raises a Racket With Melissa Rauch in Behind-the-Scenes Look (Photo)

Star of CBS sitcom celebrates school picture day (at work)

That’s quite the racket you have going, Kaley Cuoco.

“Big Bang Theory” star Cuoco shared a behind-the-scenes look at the hit CBS sitcom with fans on Monday, posting an intriguing photo of herself with co-star Melissa Rauch.

The photo, styled after a school yearbook picture, featured Cuoco with her arm around Rauch.

In the picture, Cuoco is wearing a visor and sweater while clutching a tennis racket.

The most prominent element of Rauch’s ensemble, meanwhile, seems to be a thoroughly conspicuous bit of orthodontia covering her face.

“When it’s school picture day (at work) , you pose with your tennis racquet, visor and headgear BFF @themelissarauch,” Cuoco wrote.

Couco didn’t elaborate further on the behind-the-scenes image. However, this would be as good a time as any for the show to dive deeper into its characters, such as Cuoco’s Penny and Rauch’s Bernadette, with the series preparing to wrap up its run after its current 12th season.
