The teen pop idol's flick exceeded industry expectations and nearly matched the $31.1 million opening of 2008's "Hannah Montana & Miley Cyrus: Best of Both Worlds Concert," the record-holder for music-documentary debuts.
Another love story, the animated adventure "Gnomeo & Juliet," opened solidly at No. 3 with $25.5 million.
The weekend's other new wide release, the ancient Roman saga "The Eagle," was No. 4 with $8.6 million.
