Victoria Justice takes the stage during the first night of the Summer Break Tour at the Gibson Amphitheatre on Friday night (June 21) in Universal City, Calif.

The 20-year-old actress/singer surprised fans when she brought her sister Madison Justice on stage for a performance of “Cheer Me Up”!

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.
