Rebecca Black Sneaks Into Katy Perry's 'Last Friday Night' Teaser

Katy Perry Notches Record Fifth No. 1 From 'Teenage Dream' On Pop Songs

Rebecca Black's 15 minutes of fame continue.

The singer, who rose to viral Internet fame with her much-maligned video, "Friday," appears in a blink-and-you'll-miss-it scene in the video for Katy Perry's new song, "Last Night Friday (T.G.I.F.)."

At the 16-second mark of Perry's video, below, Black is seen sitting on a couch at a party. (A source confirms to The Hollywood Reporter it's her.)

The teaser video to Perry's new song appears to be a homage to Black's "Friday," from the flipping pages in the beginning with the same font to the "fun, fun, fun, fun" refrain.

Conan O'Brien, Jimmy Fallon and Stephen Colbert have recorded parodies of Black's "Friday," while the "Glee" cast performed a rendition of the song on a prom-themed episode.
