Michael Jackson received minor burns from fireworks used in a charity concert in Munich over the weekend. (The concert raised $1.6 million for UNESCO, the Red Cross and the Nelson Mandela Children’s Fund.) The pop star was treated at a local hospital and released after Sunday’s show. Jackson’s burns were “nothing serious,” a hospital spokeswoman said. It wasn’t his first brush with pyrotechnics. He was hospitalized with second-degree scalp burns in 1984 after his hair caught fire from a smoke bomb while filming a soft-drink commercial.
