Britters works the crowd for album reaction

Britney Spears' new CD will be out soon, but the tiny singer wanted to hear some crowd reaction to her brand new tunes so she slipped into a packed New York City nightclub and had the DJ spin a few.

The capacity crowd at the hip club Show didn’t know she was there or that they were listening to Spears’ more sophisticated new music for her fourth album.

According to Kelly Cutrone, Show’s publicist, “The crowd just loved it!”

The album is due out in October.
