Pop superstar Britney Spears shocked young fans in New York on Wednesday, by paying an impromptu visit to a junior school which was closed. John Philip Sousa Junior High School in The Bronx was closed for classes because of the Jewish holiday Rosh Hashanah— so staff had to round up 20 kids, who were willing to cut short their break and head back to school to meet their idol.

The singer signed autographs, posed for pictures and smiled and joked with the thrilled kids.

One tells OK! magazine, "I couldn't say anything— it's Britney. I was shell-shocked."

Spears, who is touring the Big Apple to promote her new single "Womanizer," was forced to cut short a shopping spree on Tuesday after she was chased by a swarm of fans.

The pop star also checked out the musical In The Heights during her business/shopping trip to the city.
