Jonas hit the stage solo during the Jonas Brothers turned the poppy party tune into a slow ballad and encouraged his fans to sing along to the song that launched 43 million YouTube views.
"I think @nickjonas did an AMAZING job with Friday!" Black wrote on Twitter. "You're amazing, Nick!"
Earlier in the week, Black visited "The Tonight Show With Jay Leno" and told the talk show host that she plans on donating proceeds for the song, which is currently no. 31 on the iTunes charts, to Japan and to her school. Actor Bradley Cooper was also on "The Tonight Show" and the 13-year-old aspiring singer wrote on Twitter, "ASDFGHJKLKIOP I JUST MET BRADLEY COOPER. OMG. I almost fainted."
Since it's release, the video has been deemed "the worst music video ever" by some and others have jumped to Black's rescue, including Ryan Seacrest, Simon Cowell, Nicole Ritchie, Joel Madden and Willow Smith. On "Good Morning America," she defended her singing skills, saying, "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 song was produced by the independent Los Angeles-based company called Ark Music Factory. People magazine reports that for a fee, the company will produce a pop song and video for teenage girls who "want to get discovered."
The video became an internet sensation after Comedy Central's Tosh.o blog lampooned it under the headline, "Songwriting Isn't For Everyone" and popular Tumblr blog The Daily What made it the "Where Is Your God Now of the Day."
In the lyrics, Black starts out by detailing her morning routine before singing the layout of the days of the week, "Tomorrow is Saturday/ And Sunday comes afterwards."
