Nikki Cox, star of the WB sitcom “Nikki,” is engaged to hyperactive comedian Bob “Bobcat” Goldthwait, reports the Associated Press. Cox, 22, met Goldthwait, who is 16 years her senior, on the set of “Unhappily Ever After,” the now-defunct WB comedy in which Cox got her big break. “I had a mad crush on him and told him so,” she is quoted as saying in the March issue of Gear magazine. “He’s a really shy, sweet-natured fellow. It’s not like he’s so boisterous and outgoing.” No date for the wedding has been announced.
