Tonight's Hannah Montana/Miley Cyrus concert at Reliant Stadium set a new record...and unlike last year, everyone went home happy. 73,459 packed the home of the Texans for one last Texas-sized "Best of Both Worlds" party. The old record was shared by her and The Cheetah Girls last year when 73,295 packed Reliant Stadium, but the record was somewhat tainted as 9,773 of the 73,295 attended were refunded their money bexause they couldn't hear the concert as one of the speaker clusters in the stadium blew out before the concert.
