Black, who rocketed to fame and ridicule after her in­cred­ibly thought provoking song, “Friday,” went viral, appears in the music video for Katy Perry’s “Last Friday Night (T.G.I.F.)” Because everything she does for the rest of her life must be related to that day of the week.

In the teaser for the video, Perry’s nerdy alter ego, Kathy Beth Terry, and the 13-year-old viral video star attend to the same super cool, crazy party. The full music video will be released June 14.

Perry performed an acoustic version of “Friday” at a concert in Australia to the delight of the crowd.
