Miley Cyrus broke a Houston Rodeo attendance record on Sunday when nearly 73,500 fans packed into Reliant Stadium to watch a performance by the Disney star and her second personality, Hannah Montana.
The record she broke also was her own: nearly 73,300 fans attended the concert by Cyrus and the Cheetah Girls at the Houston Livestock Show and Rodeo last year.
