9021-Oh my, Fall Out Boy!
In the episode "Scandal Royale," Fall Out Boy performs their hit single "My Songs Know What You Did In the Dark (Light Em Up)" at a concert that Adrianna (Jessica Lowndes) also performs at. Alas, this is 90210, so the night ends in chaos!
Coincidentally, the band's sixth studio album, Save Rock and Roll, hit stores the same day as the episode airs!
90210's final season airs Monday at 9 p.m. on the CW.
