Justin Bieber got into a BIG altercation with the mother of one of his fans.  He thought the woman was taking pictures with her phone, so he demanded to see the phone.  When she didn't hand over the phone, he went through her purse and grabbed the phone.  The phone was locked and Bieber demanded she unlock the phone, so she did.  When he realized there were no photos, he started yelling at the woman, making the daughter cry.  Then Bieber yelled at her "you're embarassing yourself in front of your child, you should go away!"

What an a-hole!!
