Miami Heat's Secret Weapon

10-year-old Julia Dale is becoming a national sensation with her stirring renditions of "The Star-Spangled Banner" at the NBA finals.

She has been singing since she was 2-years-old and wants to be on Broadway one day.

Dale, who lives in Fort Lauderdale, Florida, also sings at Miami Marlins baseball games, but the NBA finals have given the pint-sized powerhouse a national stage.

She is being called the Miami Heat's secret weapon, because since she began singing for the team, they're 5 and 0.
