Who's ready for a mega musical mash-terpiece? We are! We got the chance to listen in on the making of the mash-up theme song for iParty with Victorious; the summer special that's soon to be crowned the king of all super shows. The song is a mix of the iCarly theme "Leave It All to Me" and the Victorious intro "Make It Shine". And the casts had a major blast while layin' down the beats in this righteous remix. Check it out.
