Putting the hot in hot yoga -- get it, girl!

Kaley Cuoco went to yoga class on Monday afternoon, and the 28-year-old starlet showed off her fit physique in a sheer white tank and short shorts. And the gym isn't the only place she busts her butt -- we still can't believe that she's raking in a whopping $1 million an episode for her role on The Big Bang Theory.

Kaley's been on the show since 2007, and though her co-stars Jim Parsons and Johnny Galecki were also raised to the same rate, apparently two of the lesser-known actors on the show, Simon Helberg and Kunal Nayyar, are ready to quit! "[The pay bump] just doesn't sit well with anyone," a source tells Star mag. "It has created a major rift between them and costars Simon Helberg and Kunal Nayyar, who also feel they're an integral part of the show. [But] Kaley, Jim and Johnny believe they're the real stars of the show and deserve the money."
