Beyonce Knowles apparently left her husband Jay-Z speechless when she joined him on stage in the US.
The songstress, clad in a black leather top and skimpy shorts, joined her rapper hubby on stage for their hit Crazy In Love at Brooklyn's Barclays Centre on October 6, but he got so caught up in his wife's performance that he missed his rap cue, reported MTV.com.
"Oh s***, I should probably rap here," he quipped when he realised his mistake.
Beyonce - who gave birth to the couple's first child Blue Ivy in January - also sang her song Diva, before wrapping up the show with Young Forever. It was the final night of Jay-Z's eight-show run at the Barclays Centre.
The couple, who married in April 2008, shared a kiss on stage with Jay-Z (whose real name is Shawn Carter) joking: "Of course I had to let BK touch the stage in BK [Brooklyn] - well BKC now."
Beyonce has supported Jay-Z during the hometown gigs from the first show on September 28.
