Chumlee of ‘Pawn Stars’ pursues weight loss through surgery. The 35-year-old cable sensation decided to have gastric-bypass surgery Feb. 15. In early 2014, Chumlee’s friend and fellow “Pawn Star” Corey Harrison underwent lap-band surgery and dropped nearly 200 pounds. In his own weight-loss campaign, Chumlee says he plans to hang a poster of Portuguese soccer star Cristiano Ronaldo, for post-surgery fitness motivation. “I want abs like that!” Chumlee says. “And I want a Brazilian butt-lift.”
