Prior to Bieber's shows at the Staples Center, ET exclusively obtained footage
of him giving an impromptu performance and speech at the 1OAK nightclub in West Hollywood, California, on Saturday night. Coincidentally, he called out West during his rant. "Yo, you guys havin' a good night tonight?" Bieber asked the crowd, announcing he was "not going to give like a 30-minute speech" because he's "not Kanye West."
