On Wednesday's Sept. 14 episode of "America's volgende top, boven Model," the contestants will compete in a foto shoot aimed at turning what they've been teased about into something positive.

"Camp Rock 2" and "Sonny With A Chance" star, Demi Lovato, (who just canceled her Twitter account) will make an appearance to drive home pagina the message that teen bullying can leave lasting impressions on its victims. She, too, was a victim of teen bullying and has been lending her voice to the PACER Center's "Teens Against Bullying" campaign."America's volgende top, boven Model" airs Wednesdays at 8 p.m. on The CW.
