Brooke Shields has a super-duper high-security closet at home to protect her from intruders, according to the premiere issue of Fame magazine. Taki, who will be writing a column called "The Butler's Revenge" based on gossip from disgruntled servants, says Shields has what appears to be a standard walk-in closet, but it is reinforced with half-inch steel casing, special inside locks, an air supply and independent telephone and electrical systems.
