Ever since Selena Gomez and Justin Bieber called it quits, Justin has been receiving a lot of negative attention for his bad boy ways. There have been a series of incidents when Justin's partying ways have gotten him in trouble, most recently the alleged ten thousand dollar house party earlier this month, and his alleged one night stand in Brazil. And now it appears that his ex-girlfriend is not happy about his partying ways. A source close to the part Mexican songstress tells Hollywood Life that "Selena is disgusted with the way Justin has been acting, or rather, acting out! She thinks Justin is a time bomb waiting to explode. She saw it coming and is relieved that she's out of the relationship, but she's also very sad for him, very sad."
