When she noticed a disagreement between Justin's group and some guys, she reached into her purse to get her phone and take more pics. Bieber didn't like that.
She claims he demanded the phone so he could erase any photos, but she refused. The “Believe” singer then grabbed it out of her purse and the two began wrestling over it.
He eventually got the phone, but couldn't erase the pics because it was locked. He again demanded that she erase any photos of the altercation. At that point she obliged and showed him that she didn't have any.
She then tried to explain that her 13-year-old daughter was a big fan and that they really just wanted to say hi.
The 20-year-old reportedly yelled at her, "You're humiliating yourself in front of your daughter. Why don't you just get out of here,” which caused her daughter to start crying.
