Jay Z had plenty of security surrounding him during the filming a 10-minute performance video Picasso Baby in case fans got too close, but ironically, the rapper only needed backup to get away from the other celebrities on set.

While promoting his Magna Carta Holy Grail album at midtown’s Pace Gallery, Girls star Jemima Kirke took her love for Hova a bit too far. According to NY Daily News sources, she had to be escorted off set when she took her turn to sit on the bench.

In the video, she first takes her turn on the bench, letting Hova serenade her. Wearing hot pink pants and a black top, the smiley actress still has her act together as she lets down her hair and grins away. A short time later, the video cuts to Kirke, now draped on Jay like a cheap suit as he raps to the cheering crowd.

“She was acting totally nuts!” said one witness, who watched Kirke climb onto Jay’s back and hold on tightly while the hip-hop superstar walked about, rapping to fans without missing a beat.

“She kept jumping on his back like a little monkey,” said another source.

“Someone was screaming ‘Get her off of him!’ ” says our spy. Kirke went away kicking and begging, “Let us finish!” as she was removed from the gallery.

The audience also included a group of art world stars like Marina Abramovic and celebs like Alan Cumming.
