Tuesday's edition of NBC's America's Got Talent came from St. Louis, where judges Howard Stern, Sharon Osbourne and Howie Mandel served as gatekeepers to the West for those hoping to win the show's $1 million grand prize and the chance to headline a Las Vegas production.

Among those hoping to make it past the Arch:

Isaac Brown, a beyond-adorable 6-year-old who sang the Jackson 5's I Want You Back, and impressed the judges enough to get a pass to Vegas.

"You're a superstar!" an impressed Howie told the lad, while Howard told him, "I love you already and I just met you."

"Very few people have star quality -- and you have it," a stoic Sharon told the tot.

America's Got Talent airs on NBC Mondays at 8/7c and Tuesdays at 9/8c.
