ROCK 'n' roll legend Jerry Lee Lewis has married for a seventh time in Mississippi, and the new bride is his cousin's ex-wife. Judith Ann Coghlan Lewis, 62, worked several years as Lewis' caretaker at his home, just south of Memphis - a job she said she was sent to do by her then-husband and one of Lewis' ex-wives, who were brother and sister. She said she and the 76-year-old Lewis, also known as "The Killer," never intended to fall in love. It just happened.
