"Friday" on Tuesday!

Instant web superstar Rebecca Black sang her talked-about YouTube smash "Friday" in front of a live audience on Tuesday's The Tonight Show with Jay Leno.

The 13-year-old Orange County native remains a talked-about online topic for the home-made song and video that's been viewed on over 13 million times.

Although the eighth-grader has been criticized for the heavy use of AutoTune -- and those lyrics -- in "Friday," she faced her naysayers with a smile during her live show.

"Those hurtful comments really shocked me," Black has said of the backlash. "It feels like I'm being cyberbullied."
