Justin Bieber puts immense effort into his concerts.
The 18-year-old singer kicked off his six-month long international Believe tour in Glendale, Arizona on Saturday.
Justin has worked excessively to ensure that the performances are an incredible experience for fans.
"We've been working every night," Justin told ET Online.
"On the first tour I really wasn't much involved. This time I really wanted to be involved more, because if it's everyone else putting it together, it's someone else's show."
Justin rehearses a great deal.
The star believes that it’s essential to treat himself now and again with delectable snacks.
"I really like having apples and caramel," he smiled.
Justin really appreciates the love he receives from the public.
The superstar gives back by putting on the best show he possibly can.
"I thank all the people that come out to just support me; that like my music; that just forget about their struggles at the moment; that can just come in and just have a great time," Justin said. "That's what I love."
