OK! Exclusive: Ashlee Simpson Calls Sister Jessica A ‘Drag Queen’ — Find Out Why!

Jessica Simpson is looking more incredible than ever but not everyone is loving her look right now, including her sister Ashlee!

A source told OK! magazine that Ashlee thinks Jess is taking her hardcore workouts too far and urged her to cut back on pumping the iron.

“Ashlee thinks Jessica is getting so muscular she’s starting to look like a drag queen,” the source said.

However, Jess’ extreme workout regiment is not the sisters’ only point of contention. Ashlee is also peeved about Mrs. Eric Johnson’s extreme eating!

“Jess is so rigid about her diet, all she’ll eat is steamed or raw veggies and grilled fish or chicken,” the source notes. “And when Ashlee was pregnant, Jessica nagged her about her food.”
