Donna Simpson: woman who wants to be world's fattest
Miss Simpson, 42, from New Jersey, USA, already holds the Guinness World Record as the world's biggest mum.
She was 520lbs when she had daughter Jacqueline, three, becoming the largest woman to give birth.
Now she weighs a mega 600lbs, or 43 stone, and hopes to break the 1,000lbs or half a ton mark.
Miss Simpson, who wears XXXXXXXL dresses, eats whole cakes and bags of donuts and tries to move as little as possible.
"I'd love to be 1,000lb," she said.
"It might be hard though. Running after my daughter keeps my weight down."
She runs her own website where people pay to watch her eat, or see her wash her huge body.
The cash helps fund the family's $750 a week food shop, which Miss Simpson carries out in her mobility scooter.
She met her partner Philippe, 49, seven years ago on a dating site for plus-size people.
Philippe, who weighs just 150lbs, is a self-confessed fat admirer, who will only look at a woman if she weighs over 28 stone.
But Miss Simpson, who has an older son Devin, 14, from a previous relationship, insists she's healthy.
"My favourite food is sushi, but unlike others I can sit and eat 70 big pieces of sushi in one go," she said.
"I do love cakes and sweet things, doughnuts are my favourite."
I always wondered what 'mad cow disease' actually looked like.
