Michaela Wallace is out with the music video to her new single ‘Justin Bieber’s Girlfriend’, the title track off the 14-year-old pop singer’s EP, out now on iTunes. While in Nashville, Michaela had the opportunity to meet the Canadian pop star at one of his sold-out shows, getting a chance to play video games with him backstage. “I was so nervous, but he was so cool and funny,” Wallace said. “We had a great time!” Footage from their meeting can be seen in the video for the song.
