Between Mark Zuckerberg's $100 million donation and Bon Jovi's Rock and Roll Hall of Fame nomination, it's been a pretty good week for NJ. But it's even better than that: Beyonce dropped by one of your block parties this weekend!

The "Single Ladies" singer, who just turned 29 on Sept. 4, was in West Orange visiting husband Jay-Z's mother when she happened upon the party and crashed it. In the video below, you can see her doing something called "The Wobble" with a group of awed, mouth-agape young ladies. Jeez, the last time we had a block party, the only person who crashed it was this strange old guy who was really into stoop drinking.
