Another teen pop star with a big ego and a nasty personality – wow, what are the odds? This former Nickelodeon star was the girl that a lot of people used to compare ‘bad girl’ young celebs to; it seemed like she was going to be the perfect ‘good girl’ poster-child. However, over time reports of her behavior started to surface and the world got a chance to see the spoiled diva that lurked behind her smile. From rumors of her being nasty to fans (“I hope they all [bleeping] die”) and numerous twitter beefs to her infamous donut-licking fiasco where she said “I hate America” on camera. At least we still have Taylor Swift as our ‘good girl’.
