DEMI LOVATO
7 p.m., Verizon Arena. $14.99-$49.50.
A week after she appeared on the cover of People locked arm and arm, giggling, with Selena Gomez (“The Disney stars open up about family, fun and being BFFs”), Demi Lovato goes into the books as the first to headline at newly christened Verizon Arena. (The Alltel sign went down last week.) As the latest contender for Disney’s tween queen, Dallas-raised Lovato has all the necessary bona fides: She acts, she sings and she loves Jesus. Last week, the debut of her “Princess Protection Program” movie recorded the third highest number of viewers for Disney Channel. It stars Lovato as a princess who, after a dictator grabs power, flees her country for rural Louisiana, where she teaches Selena Gomez to find her “inner princess.” That followed, by a little more than a week, the release of her latest single, an angst-y, surprisingly guitar-heavy pop blast called “Here We Go Again.” It’s also the title of her sophomore album, due out July 21. Then there’s “Sonny with a Chance,” the latest of Disney’s meta wish-fulfillment TV shows. Here Lovato plays the star of a TV show. It’s about “following your dream,” Disney has said. David Archuleta, the apple-cheeked runner-up of the seventh season of “American Idol,” opens with songs from his self-titled debut album.
