Kaley Cuoco Stuns in Red at Beverly Hills Charity Event – and Wears Skin-Baring Outfit on Stage

Kaley Cuoco is a vision in red.

The Big Bang Theory star stepped out on Wednesday at the Alzheimer's Association's "A Night at Sardi's" event in Beverly Hills.

Cuoco wore a sleeveless, sparkling Naeem Khan red dress with cutouts at the sides – giving a glimpse of her toned abs and back.

The 30-year-old stayed true to the vibrant color on the event stage as well, sporting a red crop top, tiny black shorts and fishnets to perform "Dance 10, Looks 3" from A Chorus Line.



Cuoco posted a photo of the skin-baring ensemble on Instagram, noting that she "nailed" the performance.

Later, the actress joined Big Bang costars Jim Parsons, Simon Helberg, Melissa Rauch, Johnny Galecki, Mayim Bialik and Kunal Nayyar for the event's finale. Together, the group delivered a colorful performance of "You're the One That I Want" and "We Go Together" from Grease.

The group sported a '50s-style wardrobe and were surrounded by sock-hop dancers.

Afterwards, the stars took to their respective Instagram accounts, posting photos of the costume-clad cast.

"We'll always be together!" Rauch captioned an image of the crew.

Bialik uploaded a shot of herself alongside Rauch and Cuoco, including the caption, "Girls only #sardisfinalshow."
