MTV’s inaugural O Music Awards are being held Thursday night, not Friday, but that won’t stop YouTube superstar Rebecca Black from appearing at 11 p.m. ET/8 p.m. PT from a surprise location in Las Vegas.

Black’s “Friday” topped 100 million views earlier this month — it had tallied more than 122 million at the time of this post — and the 13-year-old singer celebrated with a Hollywood billboard.

The OMAs, recognizing creativity and technology in digital music, will be held Thursday night on MTV Music & Logo Group platforms including MTV.com, VH1.com, CMT.com, and LOGOTV.com.
