Rebecca Black sings 'Friday' on 'The Tonight Show'

“Friday” singer Rebecca Black continued to turn her Internet punching bag status into a real music career Tuesday night with a performance on “The Tonight Show With Jay Leno.”

In addition to sharing her song with the late-night crowd, the 13-year-old viral video star voiced her appreciation for celebrities who’ve taken the time to defend her from the steady stream of online abuse she’s received.

“Ryan Seacrest has been amazing through this whole thing,” Black told Leno. “Yeah, and oh my gosh, (Simon Cowell) wants to meet me! That’s so cool.”

Black also revealed what she plans to do with any profits she earns from releasing what some have called the worst song ever.

"I'm donating the proceeds to Japan and to my school," the teen said with a smile.
