The Show Must Go On! Britney Spears Bummed Over ‘Half-Empty’ Last Vegas Show, Production ‘Scrambling’ To Fill Seats

Britney Spears recently signed a $30 million contract to extend her “Piece of Me” Las Vegas residency until 2017. But RadarOnline.com has learned she might be regretting that decision. Declining ticket sales and low audience energy have the pop princess less than pleased, according to an insider, and staffers are now “scrambling” to find a solution that will bring the show back to its heyday.

As RadarOnline.com reported last week, online ticket sales indicate that the once sold-out show will have a half-empty theater for the several upcoming performances.

And when Spears found out, an insider tells RadarOnline.com, “She said that there was no way in hell that she would perform to a half-empty theater,” because she thrives off of audience energy.

Now, the source said, production staffers are scrambling to fill seats with promotions like the recent “Britneyween” Halloween special, and the upcoming “Britney Day” performance, where anyone sharing Spears’ name can get a free seat.

Behind the decline, the insider says, is "an issue of exclusivity.”

“When everyone thought that they had to go see her or else, the place was packed. But now that it is long-term, everything seems to have changed,” the source explains.

And Spears doesn’t have to take it. Though the star just got a raise to $475,000 per show, the source says, “Britney doesn’t need the money. The security of two more years is great for her dancers, crew, and everyone involved, though, so she’ll stick it out.”
