Amusing footage has emerged of the moment a fan of Kendrick Lamar froze on stage after being called up from the audience - before another tries to jump up and take her place.<br /><br />The filmer wrote online: "He gave three fans a chance to come on stage and rap his lyrics with him... But only two of them could hang... And it it wasn't this chick. <br /><br />"While Kendrick is trying to comfort her and get her off stage, a crazed fan jumps on stage but is soon escorted off."<br /><br />++CLIENTS NOTE: Edited for swearing++
