Kaley Cuoco took her sweet ride out on the town on Sunday when the actress attended the Stand Up For Pits charity event in Los Angeles at The Improv on Sunday. The Big Bang Theory actress showed up to the event in her $250k Mercedes-Benz SLR McLaren.

Stand Up For Pits is a pit bull terrier animal rights group, which focuses on ending breed-specific legislation and dog-fighting.

Opting for a low-key ensemble, the 28-year-old donned jeans and a comfy looking sweatshirt with the words "Giddy Up" emblazoned on it. That's a cozy look for a chilly Los Angeles evening.

The star hosted the night's comedy show which featured performances by Whitney Cummings, Bill Burr, and Stand Up For Pits founder Rebecca Corry.

Fun stuff!
