SPOTTED: Kaley Cuoco and her Big Bang Theory cast came out last night in support of the 22nd “A Night At Sardi’s” To Benefit The Alzheimer’s Association–the event which was held at The Beverly Hilton Hotel on Wednesday (March 26) in Beverly Hills, Calif.

Kaley, who was wearing a long, white, frilled Philosophy dress paired with Jimmy Choo shoes, was joined on the red carpet by her sister Briana Cuoco and husband Ryan Sweeting. Her Big Bang Theory co-stars Jim Parsons, Johnny Galecki, Mayim Bialik, Melissa Rauch, Simon Helberg, and Kunal Nayyar all showed up for the annual Alzheimer’s Association event.

Also spotted at the event were Masters of Sex and Mean Girls star Lizzy Caplan, who daringly bared her flesh in a black lace jumper, and 2 Broke Girls blonde bombshell Beth Behrs who got photobombed on the red carpet by co-star Jonathan Kite.
