A US woman is said to have the widest bum in the world, but she still wants it bigger because it is her favourite asset, which draws her a whopping 90,000 pounds a year.

Dionne Washington has the massive bottom, which is 5ft 3ins across and weighs a whopping 22st, but still she wants it grow more.

"I am literally sitting on a fortune. My bum must be the widest in the world and it earns me over 90,000 pounds a year. I used to hate it, but now it's my fave feature," the Sun quoted the 35-year-old as saying.

Washington, whose posterior at its widest point is 14ft 9ins around, has a total weight is 35st with the BMI of 85.

She also runs the risk of suffering from high cholesterol, diabetes and heart problems due to her weight, but she seems hardly concerned.

"I'm not concerned. I love my body and wouldn't change a thing," she said.

Washington claimed that she consumes a shocking 9,000 calories a day to maintain her bottomĀ -- which is more than three times the recommended intake for women.

"The more I eat the bigger this beauty gets," she added.
