Back in the old days — you know, the 1900s — great teen idol names were adopted more than born. Think Sandra Dee (nee Alexandra Zuck), Lulu (Marie Lawrie), Pink (Alecia Moore), Scary Spice (Melanie Brown).

Now comes Victoria Justice, a 19-year-old from Hollywood, Fla., who was handed that name at birth. Her parents might have been hoping she’d become a superhero. Close. She’s the star of her own show, “Victorious,” which airs on Nickelodeon and has spawned a robust singing career and even a few fashion trends — that’s why you see so many pre-teenyboppers in layered tank tops, boots, and feathered earrings.
