Her July 31 Hollywood Bowl concert has had to be moved to the Great Western Forum in L.A.because the production is too large, the Los Angeles Times reports.

The good news is a July 30 show, also at the Forum, was added to accomodate more fans.

As was the case with a July 26 cancellation of a sold-out show at Red Rocks Amphitheatre near Denver, production changes made since the start of the tour caused the show to “outgrow” the venue.

The added elements involve Spears “flying” over the stage – similar to a highlight of ‘N Sync‘s stage production – and a simulated bedroom set, a production manager for the show told the Times.

Ticketholders for the Hollywood Bowl concert can exchange them for comparable seats at the Forum at the point of purchase. Remaining seats go on sale to the public July 21.

The teen sensation is on the road in support of her second album, Oops! I Did It Again.
