American Idol's Mario Vasquez quits, Nikko back

In a dramatic turn, American Idol Mario Vazquez has quit the show citing personal reasons and will be replaced by recently booted Nikko Smith. Mario was one of the favorite men in the competition along with rocker Bo Bice and soulful Anwar Robinson. Nikko was voted off in last week's elimination episode and will probably not last long in his return. Nikko is the son of baseball Hall of Famer Ozzie Smith.
