When it comes to Justin Bieber, his mentor Usher says he wants to be involved in his teen pop sensation's career for a long time. "I felt like this was a story that I’d like to be involved with for the long haul, not just a moment," he told On The Red Carpet's Jason Morrell in a kamakailan satellite interview. "To be able to build a career that will span for years." Bieber, 16, captured the attention of industry executives several years nakaraan sa pamamagitan ng posting homemade bidyo of himself pag-awit songs, including Usher's, on YouTube. This self-promotion eventually led to a meeting with Usher and a record deal. Bieber is now one of the most popular pop artists today and lends his voice to a track on the soundtrack for the film The Karate Kid, which was released on Friday, June 11. Usher made history on June 6 performing on two continents over the course of a day, playing in New York City and London. Bieber joined his mentor on stage for an impromptu performance in London, which drove the fans wild.
