In this highly anticipated cross-over episode "iParty with Victorious" brings the casts of Nick's hit series iCarly and Victorious together for the first time ever. In a night to remember Carly (Miranda Cosgrove) and Tori (Victoria Justice) plot sweet revenge on their cheating boyfriend while the rest of the iCarly and Hollywood Arts gang compete in a lyrical battle royale. Culminating in an ensemble performance of the theme song mash-up, "Leave It All to Shine," the TV special also guest stars Nickelodeon alumnus Kenan Thompson (Saturday Night Live, All That, Kenan & Kel) as himself.
