Famous for her online music video "Friday," the 14-year-old Internet sensation won an MTV Teen Choice award for Choice Web Star last weekend.
However, she said the song and the attention it received made her the target of non-stop bullying at her Anaheim Hills school, so she is now being home-schooled, KTLA News said on its Web site.
"When I walk by they'll start singing 'Friday' in a really nasally voice," she told ABC's "Nightline" of her classmates. "Or, you know, they'll be like, 'Oh hey, Rebecca, guess what day it is?'"
KTLA quoted Black as saying she has received death threats related to the song's popularity.
What grade Black is in or what school she attended were not reported by KTLA.
