Victoria Justice is striking out on her own with a new single, "Gold," and a new, more grown-up sound. The former Victorious star, now 20, is leaving her Nickelodeon character behind and making music under her own name. We caught up with Victoria this week as she rehearsed for the Summer Break Tour — which features her alongside Big Time Rush — and got a sneak peek at what fans can expect from the string of shows. Victoria also filled us in on working with the producers behind Justin Bieber and Christina Aguilera, how she unwinds on the tour bus, and whether we might see her pop up on the Victorious spinoff series Sam & Cat.
