Kaley Cuoco joined Kirsten Bell at the Beverly Hills Hotel yesterday evening for the 20th anniversary of the Alzheimer’s Association event, ‘A Night at Sardi’s.’

The blonde beauty chose a sweet Tadashi Shoji Spring 2012 dress.

Her vibrant yellow sleeveless tiered cocktail dress with a pleated tulle skirt and ribbon trim was great choice for Kaley as her red carpet choices can be a tad questionable at times.

Yellow is definitely having a red carpet moment right now, as Kaley is just the latest star on the long list of celebs to sporting the bright hue.

A tight, wavy ponytail and nude lippie complete the look.
