Victoria Justice wants to turns herself into a career actress and singer.

“I’m 19,” the native of Hollywood, Florida, says while promoting her first big-screen starring role in Fun Size. “I’ll be 20 in February. I’m growing up. Hopefully, I can take that audience (from Nickelodeon) with me and also be approachable to a new audience.”

In Fun Size, Justice plays a high schooler who babysits her eight-year-old bratty brother on Halloween. The movie opens Friday. Justice says shooting Fun Size on location in Cleveland was an interesting contrast to shooting Victorious and staging her first U.S. concert tour last summer.
