He didn't come to Jersey Shore looking for love, but that's exactly what Ronnie Ortiz-Magro found when he met fellow castmate Sammi "Sweetheart" Giancola. The muscular "Guido" was born in 1986 and grew up in the Bronx, New York. His hot-headed temper led to a series of physical fights during the show, the final of which landed him in jail.
Still, the gym-loving reality star made viewers laugh with his "Ron-Ron Juice" and his budding relationship with Sami "Sweetheart". During MTV's reunion special in January 2010, a clip of Giancola kissing fellow castmate Mike "The Situation" Sorrentino and giving another guy her number aired, shocking Magro. "I cut girls quicker than barbers do. She can be right on the list. I really don't care," he said. The pair dated on and off for a year-and-a-half before calling it quits in 2011.
