The Believe tour kicked off in Glendale, AZ last night to a sold out crowd at the Jobing Arena. One of the highlights of the night came when Justin Bieber delivered a heartfelt performance of "One Less Lonely Girl" in memory of Avalanna Routh. Routh was a 6-year-old fan of Bieber's who passed away earlier this week from a rare cancer. The performance featured a picture montage of Routh, including moments she shared with the Biebs. Check out this performance of "One Less Lonely Girl" from last night below:
