The 18-year-old superstar has chosen a new young YouTube singer to support. Bieber tweeted to his over 25 million followers Tuesday links to three music videos of 13-year-old Madison Beer.
And finally, Bieber tweeted a third video to 26-year-old "Call Me, Maybe" star Carly Rae Jepsen. Bieber helped launch Jepsen's career when he shared a music video of himself with pals Selena Gomez and Ashley Tisdale dancing to her song.
