Beyonce took the stage to perform with her husband Jay-Z during the final show of his opening run at the Barclays Center on October 6.
Beyonce performed her 2008 hit single, "Diva" followed by her hit with her hubby, "Crazy in Love."
She also later took the stage to close out the show with, "Young Forever.”
The BK fans weren't the only ones in awe of Queen Bey’s surprise performance. Jay-Z ended up missing his cue to come on stage for “Crazy in Love,” and Bey had to start his rap! “Oh sh– I should probably rap here,” he said as he walked on stage.
Later, Hov gave his wife a playful slap on the behind as she exited the stage. "Of course I had to let BK touch the stage in BK-- well BKC now," he joked.
