Bad, bad Bobby Brown — husband of megastar Whitney Houston — will spend the next 36 days cooling his heels in a Florida jail after admitting he violated probation by failing to take a drug test. As he was being led back to the Broward County jail yesterday, a downcast Brown blamed it all on the booze. "To my fans, people who bought my record and think I wasn't being a man about the situation, I do have a disease — I have alcoholism," he said. Brown has been in the jail near Fort Lauderdale since May 10 when he was picked up at Newark (NJ) International Airport — returning from a Bahamas vacation with Houston — on an outstanding warrant for drunk-driving. —New York Post
