Victoria‘s pal and former Victorious co-star Avan Jogia missed the show, but was sweet enough to send well wishes to the singer on Twitter: “Hey @VictoriaJustice heard u killed it last night. Sorry 2 have missed the show, knock em dead on that tour my friend.”

Earlier that day, Victoria went for a more casual look during the Summer Break Tour rehearsals.

FYI: Victoria is wearing a Brian Lichtenberg jacket, Urban Outfitters top, American Apparel pants, and Aldo shoes.
