Fans were in for a surprise when they hit up an in-store signing with Victoria Justice this Friday.

In a real-life follow up to her "All I Want Is Everything" video, she met up with her hot costar Dean Stanland and performed with a flash mob!

Since the video's release, fans have discovered there were hidden clues within the video (a URL, a working phone number) that indicated Dean was a “real” character who was interacting with Victoria and the Victorious castmates through Twitter and Facebook. This romantic comedy continued to unfold until yesterday, when fans were told to show up at CityWalk to see the final chapter.
