Justin Bieber crashed Ellen today and took over the show as the teen star is known to do. He interrupted the monologue while Ellen was pushing copies of her girlfriend Portia De Rossi’s book Unbearable Lightness with a copy of his own book First Step 2 Forever in hand. Ellen had him sign it then they did a dance together through the crowd to Usher’s “Yeah.” The real highlight came during a brief sit down with Ellen when Justin broke out into an impromptu version of Katy Perry’s “Teenage Dream.” Check out the clip here!
