FALL OUT BOY PERFORMS --- Jordan's (guest star Robbie Jones) sister Elizabeth (guest star Keke Palmer) gets into trouble with an out-of-control Royal, so Naomi (AnnaLynne McCord) helps out by taking the heat to protect Elizabeth's reputation. Silver (Jessica Stroup) is called in to see her doctor about some test results and Annie (Shenae Grimes) decides to get over Liam (Matt Lanter) by going to Paris for a book tour. Meanwhile, Adrianna (Jessica Lowndes) performs after Fall Out Boy at a big event, but the concert ends in chaos. Michael Steger and Tristan Wilds also star. David Warren directed the episode written by Terrence Coli and Paul Sciarrotta (#521).
