And this is why putting kids in the public eye- especially in entertainment- can be so difficult. Youtube sensation (and unfortunately, not in the best way ) Rebecca Black admitted she cried over all the “nasty comments” about her song ‘Friday.’ “Those hurtful comments really shocked me,” Black, 13, tells the  Daily Beast . “At times, it feels like I’m being cyberbullied.” What was the worst comment? ‘I hope you cut yourself, and I hope you’ll get an eating disorder so you’ll look pretty,’ ” Black said on Friday’s  Good Morning America . “When I first saw all the nasty comments, I did cry … I don’t think I’m the worst singer, but I don’t think I’m the best.” Above is her interview on ‘Good Morning America.’ Below, you can see that although Rebecca may be upset about the criticism, she’s taking advantage of the attention. Listen to her message to pop superstar Justin Bieber : You can’t blame her for going for it- LOL!
