Justin Bieber, 16, to release memoir, was serenaded by Shaquille O'Neal
One of those fans could be basketball star Shaquille O'Neal, who recently serenaded Bieber during a sound check at the singer's recent concert in Arizona.
"Justin Bieber, yes I love you, I hope you like me, I'm your biggest fan," O'Neal sang at the event.
Bieber's memoir is called Justin Bieber: First Step 2 Forever: My Story and its publisher HarperCollins said it will reveal the teen sensation's "amazing journey to stardom."
Bieber grew up in Canada and captured the attention of industry executives several years ago by posting homemade videos of himself singing songs, including Usher's, on YouTube. This self-promotion eventually led to a meeting with Usher and a record deal. He now lives in Atlanta with his mother.
His fans are loyal and many follow him everywhere. Some have even threatened women pictured with him, such as Kim Kardashian, and have even become so unruly that they have prompted the cancellation of his concerts.
When the singer landed in New Zealand earlier this month to promote his music, screaming fans who had been waiting for his arrival crowded him so much that even tightened security could not stop his mother from being knocked down to the ground. His hat was also stolen and later returned.
Usher has said he wants to be involved in Bieber's career for a long time. Bieber is currently touring the United States and says he plans to soon perform in other countries. Bieber is also set to make his acting debut on the season premiere of CSI: Crime Scene Investigation, in which he plays a "bad man".
