If there's anything Beliebers can expect from their idol, it's incredible live performances. Even though Justin doesn't want to take selfies with people, and has deleted his Instagram account, he tries his absolute best when he's on stage. He performed a live, broadcasted, acoustic set in BBC Radio 1's Live Lounge the other day. Although he seemed to be fine, he sang his set then apologized to fans over Twitter. He felt his performance and answer to the Q&A weren't up to his standards.
Aw! Justin was nervous about his performance, maybe it was because he was broadcasting to millions, while also being in an intimate setting. That seems super stressful to me. Must be super intimidating. It just goes to show that even the biggest stars like Justin can go through nerves and not feeling like you were up to your own standards just like all of us.
