This woman has quite the backstory.

Meet Sarah Massey, 33, a married mother of two who is the world record holder for world’s biggest butt.

The Chicago woman’s posterior is so large she has to wear pants sized 10XL. Her waist is a rather immense 84 inches.

Massey says he tries to eat well, but struggles with “portion control.”

She would like to lose weight, claiming her keester causes back pain. Her husband also wants her to shed some pounds, but not any of her signature spunk.
