Jimmy Buffett, 53, has set his singing aside for a minute as he prepares to open a new island-themed restaurant, "Cheeseburger in Paradise," reports the Associated Press. But Buffett's no stranger to the biz -- he already owns one restaurant chain, "Margaritaville," named after his hit song, and is also opening two Krispy Kreme doughnut shops in Palm Beach County, Fla. "Cheeseburger," named after one of Buffett's well-known songs, is expected to open next year. The location has not yet been decided.
