Former plus size model and anorexia survivor Crystal Renn’s dramatic weight loss has sparked outrage in the plus size community who have supported her and helped launch her career, RadarOnline.com is exclusively reporting.

“Everyone rallied around her and now she’s turned against us,” PLUS Model Magazine Editor-in-Chief Madeline Jones told RadarOnline.com in an exclusive interview. “We have been betrayed by her.”

As RadarOnline.com previously reported, the 5’9” beauty was a shadow of her former self when she walked the red carpet in a skintight scarlet Zac Posen gown at the New York premiere of Madonna’s W.E. on Monday night, prompting fears she has fallen back into bad habits.
