Someone better slip Paula Abdul a Xanax: American Idol front-runner Mario Vazquez has abruptly dropped out of the competition. In an exclusive interview with TVGuide.com Sunday night, Vazquez said he quit to "take care of some personal issues with my family in New York. And with Idol being a live show, it just wouldn't have worked out schedulewise." The 27-year-old added that his withdrawal had nothing to do with Idol or Fox. "I'm healthy, I'm fine," he said. "It's just a personal family thing." However, Vazquez' mom, Ada, knew nothing of her son's decision. "I don't know his reasons," she told the New York Post. "But whatever they are, I respect him for it and will be very supportive." Vazquez' coveted Top 12 slot will be filled by Nikko Smith, who returns after being eliminated on last Wednesday's show.
