Last week we reported that K-pop superstar Rain would collaborate with action superstar Jackie Chan for the MV for Hip Song. Well, the MV has finally been released! This MV will help promote Jackie Chan's upcoming movie Karate Kid, a remake of the 1984 original. This MV will promote the movie to the Korean audience as Rain is reportedly good friends with Jackie Chan. Will Smith's son Jaden Smith co-stars in the movie with Jackie Chan. The movie is slated to open in theaters on June 10th. Thanks to Sewia for the tip.
