What kind of troubleSelena Gomez gets herself into in the next episode of “Wizards of Waverly Place” has been teased through a series of new stills. The newly-released photos see the 17-year-old as Alex Russo in a puffy baby blue dress. Some of them pictured her being stuck in a dollhouse, while one captured her giving her on-screen brother David Henrie a hug. The “Doll House” episode will have Harper coming to live with the Russos after she learns her family is moving away. While Alex and Harper clean out the basement to make room for Harper’s stuff, Alex shrinks herself down to fit in her old doll house. But, just as she does so, her parents give the doll house away. “Wizards of Waverly Place” itself centers on the Russo family whose three children, Justin, Alex and Max, are wizards in training. Jake T. Austin, Maria Canals Barrera, David DeLuise and Jennifer Stone join Selena Gomez and David Henrie in the cast ensemble. The “Doll House” episode is scheduled to air next Friday, November 20 at 8 P.M. ET/PT on Disney Channel.
