We're obsessed with the scandaliciousness on 90210. But the drama doesn't end when the cameras stop rolling. In fact, some of the show's producers and co-stars are allegedly worried about Jessica Stroup and Shenae Grimes's super skinniness. "The girls were all skinny when they started, but they're definitely thinner now," a show insider tells Us Weekly. It's gotten so bad that some of the guys on the show are said to be planning an intervention. "They want the girls to gain weight," a show source tells Us Weekly. "They are trying too hard to be skinny, and it's started to wear on them. It's just not healthy." Adds another insider: "I've never seen Jessica or Shenae eat." Yikes! Nat better fire up the grill at the Peach Pit and get these girls two cheeseburgers!
