Leonardo DiCaprio played the part of paparazzi -- or celeb-obsessed fan -- in a prank on "Wolf of Wall Street" co-star Jonah Hill, according to video that has surfaced online.
DiCaprio is seen in the video, apparently shot by paparazzi, riding a Citi Bike with a crew of about four friends. A few moments later, the group is walking on the sidewalk where DiCaprio spots a familiar face. He runs at Hill with his phone out, startling the bearded actor. A hug comes next.
