Justin Bieber is successful because he is a brilliant singer.
He began his career at a young age of 13 years old. To become successful he must have had to practice really hard since he was little. He is now 21 years old, so he has been famous for 8 years now.
He has performances all over the world such as England, Canada, America and even New Zealand. When he is on stage he sings and dances for the audience. Taylor Swift and Justin Bieber are currently tied, both having 45 music awards.
My favorite song by Justin Bieber is "Never Say Never". He says the word 'never' 62 times in two minutes.
