Beyonce Crashes Block Party After Visiting Jay-Z's Mom

Jay's lady watching from the sidelines at Bonnaroo.

Let me just say, first of all, that I lived in one of the Oranges, briefly, a couple of years back and I NEVER saw Beyoncé or Jay around those parts. But, I digress.

After a quick visit to her husband Jay-Z's mother's house in West Orange, New Jersey, according to Perez Hilton, Beyonce not only crashed a block party, she joined the dance line as well.

Wearing black fitted pants, a white tee and sky-high camel-colored heels, B joined a group of women as they danced in the middle of a street, all the while being recorded (was that you behind the lens, Jay?).
