If all those wild theories are true and Elvis Presley really is alive, he's going to become a grandfather in the spring. Lisa Marie Presley, 20, who was married just last week to musician Danny Keough, 23, at a Church of Scientology ceremony, is expecting a baby in the spring. The announcement was made Tuesday by her mother, actress Priscilla Presley, who last week broke the news about Lisa Marie's Oct. 3 wedding. "Lisa and Danny have been talking for the past year about getting married and starting a family," Priscilla said. "I couldn't be happier for the two of them at this very special time in their lives." The newlyweds are honeymooning in the Caribbean.
