PHOTOS & VIDEO: Beyonce Makes Surprise Appearance at Jay-Z's Final Barclays Concert

For the last concert of Jay-Z’s eight-night run at Brooklyn’s Barclays Center, the rapper pulled out all the stops.

“I'm so proud to be here,” said Beyonce as part of her “Diva”-“Crazy In Love” medley -- with hubby Jay joining the singer for the latter number, as he did on the 2003 track.
