Colbert and co. are scheduled to perform the 13-year-old's debut song on April 1 on the Jimmy Fallon show to help raise money for DonorsChoose.org, a charity that helps classrooms in need. Colbert recently raised more than $26,000 for the organization by selling a portrait of himself.
The goal with the performance is to match the previous donation. If fans can help match $26,000 by Friday, Colbert will perform the song. As of press time, more than $4,800 has been donated.
Despite the show's air date, Jimmy Fallon insists this is a not an April Fool's Day joke but teased, "It's a great cause, and it reminds me of why Stephen and I became best friends for six months."
Black, whose song 'Friday' recently exploded onto YouTube, has already gained more than 63 million views, following in the footsteps of Justin Bieber, as well as newcomers like Greyson Chance and Cody Simpson.
With her newfound fame, Black has come under attack online with more than one million YouTube comments -- some tearing down the young star and her song. She also received more backlash after saying she'd love to sing a duet with Bieber one day. Fortunately, some artists have come to the young singer's defense.
"I thought it was great," Chris Brown after hearing the song. "I'll be jammin' to it on Friday, Friday," he said. Lady Gaga even called Black a "genius' and "anyone that's telling her she's cheesy is full of s---."
