The 13-year-old released her debut track 'Friday' online on Monday, but has had to endure a heavy backlash from the online community over the track's simple production, lyrics and use of auto-tune.
The music video for the song went viral earlier in the week, gaining around 16 million views on YouTube.
"After seeing it go from 4,000 views to 70,000 views in one night, and then waking up and it was at 200,000 views - that's when I realised this was going to be big," she told Good Morning America.
The clip has attracted a lot of hate, with viewers often posting vicious and personal comments against Black. After reading some of the comments, she responded: "It doesn't bother me."
The pop newcomer revealed that the meanest thing she had read about herself was: "I hope you cut yourself and I hope you get an eating disorder so you'll look pretty - and I hope you go cut and die."
She said of the song's response: "When I first saw all of these nasty comments I did cry. I felt like this was my fault and I shouldn't have done this [song].
"Now I don't feel that way."
Responding to criticism regarding the use of auto-tune on the track, Black asserted: "I think I have talent on some level. I don't think I'm the worst singer, but I don't think I'm the best singer."
The online star concluded by revealing that her dream duet would be with Justin Bieber, proceeding to make a plea to the Canadian star for a collaboration in the near future.
