Beyonce is a Powerhouse Player

A solo Beyonce catches a departing flight out of JFK airport in New York City on Wednesday afternoon.

Last night, the 27-year-old singer/actress made a surprise appearance at Power 105.1 Powerhouse concert in New Jersey.

At the end of husband Jay-Z‘s headlining set, which also featured recently recovered DJ AA, Beyonce took the stage to perform a shortened version of her hit song “Single Ladies.” Before heading offstage, Beyonce threw up the Roc-A-Fella sign (Jay-Z‘s label).

Beyonce is set to hit the MTV Europe Music Awards stage next month.
