LOS ANGELES—Waitress and aspiring singer Olivia Martin, 21, had her hopes of stardom dashed by a panel of washed-up celebrities Monday. "All I've wanted to do my whole life is bring people joy with my singing, but Martika said I should stick to serving pancakes," said Martin, whose performing also received poor reviews from former MTV VJ Alan Hunter and Saved By The Bell's Mario Lopez. "This was my big break, but I blew it." Martika, who sang the 1988 hit "Toy Soldiers," said Martin lacked stage presence and didn't have "that special something it takes to be a star."
