On Thursday Justin Bieber visited BBC Radio 1's Live Lounge in Los Angeles to perform and acoustic set. The set was fantastic, displaying a range of music including Tupac covers, Tracy Chapman covers, and some of his own songs. The set lasted for a half hour and also included an interview portion where it was obvious he was nervous. Bieber later apologized on Twitter saying "I don't usually get nervous but tonight I was thrown off and I was. Sorry about that. Really wanted to be my best.
