According to a Dailymail report Sarah has to wear extra large trousers and once managed to crack a toilet bowl just by sitting on it but says she is proud to have one of the world's largest posteriors.
The Chicago mother-of-two's derriere measures an impressive 7ft in diameter and sometimes proves too large to fit through doorways.
But despite being proud of her record-breaking rear end, 32-stone Ms Massey admits that living with a super-sized bottom isn't always easy and receives £750 in disability benefit each month as a result of having limited mobility.
"I went through a stage of worrying what people think, but now I want to show the world I am proud to be me.' Sarah 33 said.
And after discovering an online community of men who appreciate curvy women, Sarah says she has no shortage of admirers.
She explained: 'It began when I took pictures of myself to document my weight loss and a photographer friend put them on Facebook.
'They got so many likes that he asked if we could do some modelling pictures, then those pictures went viral.'
But while she is comfortable with her dimensions, filling her wardrobe is expensive and requires serious planning.
'Because of my size I can't ever find outfits in normal stores. My top half is a 7XL and my bottom half is 10XL so I have to go to specialists.
'I buy most of my clothes online because there are few plus-size stores with big enough clothes. Larger outfits are expensive so I can spend up to £400 per month on clothes.'
And her problems don't end with finding clothes. Thanks to her ample bottom, she finds it difficult to perform even the most basic chores.
With most doorways I have to go in sideways - I do the little wiggle dance to get through,' she explained.
I've broken chairs before and I once broke a toilet bowl I was sat on at the theatre - it was awful.'
However, now Sarah is taking steps to tackle her mobility issues with workout sessions to help her lose weight.
Although I love my butt I would like to make it just a little bit smaller,' she confessed. 'The size that it is causes back problems- even sitting down on a chai can be painful.'
And although Sarah says large posteriors run in the family, she admits that her unhealthy junk food diet doesn't help.
Apart from my younger sister, the women in my family all have large behinds - I only eat between 1,500 and 2,000 calories per day.
However do have a problem with portion control and I sometimes get tempted by ice cream - that's my weakness.'
Growing up Ms Massey says she was constantly teased because if her developing behind - and was only chatted up by older men.
Guys my age weren't interested in me - they liked my skinnier friends. Old guys would hit on me because they appreciated my body.
Because of that I always ended up in relationships with guys 10, sometimes 20 years older.'
Despite the negative comments and difficulties fitting through the door and into regular clothes, Sarah says she has no regrets and hopes to inspire other women.
'I'm trying to make the most of what I've been given and being confident about who I am makes me happy,' added Ms Massey.
'If I can inspire others to embrace their curves and be proud big, beautiful women, I would be very happy"
OMG is all I can say but that must be a a bit unhealthy..
