In the early 1980s, Rob Lowe, Charlie Sheen, Robert Downey Jr., and Sean Penn were all friends at Santa Monica High School. Also in their crowd? Holly Robinson—and, of course, Emilio Estevez. Lowe wrote about those teenage years in his best-selling autobiography, Stories I Only Tell My Friends, and talked about his old pal Sheen on Access Hollywood last year. “We went to a big high school, and I can remember Charlie, for some reason, was wearing a bulletproof vest to school because he thought the gangs were going to get him. Charlie has some thoughts—there’s no two ways about it.” And then Lowe added this somewhat unbelievable memory: “We were both nerds, man. I am telling you—he wanted to be a baseball player.”
