She's been regularly working out since splitting from her husband Ryan Sweeting in September. And Kaley Cuoco, 29, displayed the results of her efforts as she stepped out for the Fallout 4 game launch party in Los Angeles on Thursday night. The US actress displayed her trim pins in a pair of thigh-grazing, figure-hugging hotpants, which accentuated her toned curves.
