WORCESTER - The before and after photos of celebrities examined by a group of Sullivan Middle School girls last week were striking. Minus the Photoshop editing, Kim Kardashian has cellulite, Jennifer Lawrence has curvy thighs as well as noticeable abdominal and arm muscles, and Beyonce has a broader nose and darker skin.

"She looks really white," one student commented about the edited version of Beyonce Knowles, who is African-American.
