Beyonce Crashes New Jersey Block Party

New Jersey residents were treated to some of Beyonce's (non-choreographed) dance moves from this past weekend as the R&B diva joined a mass of girls as they did the "cha cha slide" (or some version of a slide) at a block party in West Orange, NJ. Apparently, the couple happened to be visiting Jay-Z's mother, Gloria Carter at her north Jersey home -- about 25 miles from Jay's old Brooklyn neighborhood -- on the same day of the festivities and Bey decided to join in on the fun.

In other Beyonce news, the singer will reportedly drop a new single in three weeks, according to tweets from producer Los Da Mystro. Bey has yet to confirm the rumored upcoming single and album, but Ne-Yo, Sean Garrett and Jim Jonsin have all spilled the beans and discussed that they've written and produced new material for superstar.

Until then, check out the footage from the block party after the jump.
