The famous behinds, which measure 102cm each, have helped the duo amass over 1.1 million followers on Instagram.

The Argentinian pair, from Miami Florida, can afford to sustain a life of luxury. They have even had over £41,000 worth of surgery completely free because they advertised the results on social media.

They had to transfer three kilograms of fat from other areas of their bodies to adequately enlarge their bottoms.

The circumference of the 'Belfie Queens'' behinds have subsequently swelled to over a metre in thickness thanks to their dedication to plastic surgery. 

After becoming famous on Instagram the sisters are now looking to expand their businesses.

They take up to 150 selfies every day and have recently begun posting on the 'Supe' app, where users pay for pictures and video clips. 

Nadia said the app, which has only existed for two months, is similar to SnapChat but each image or video has a price.

Between Supe and Instagram 'we make between $15,000 and $17,000 a month each. In total it is around $30,000 together', she added.

Her twin sister Dana said: 'We have the most famous bottoms on Instagram and the bottom sells a lot.

'We've had a lot of work offers because of it. We are the selfie queens and we've made a successful business out if it.'

Both entrepreneurs have not just had a lot of work done on their bums.

The pair have also had breast enhancements, lip fillers, porcelain veneers and have regular botox sessions.

But the women insist they still had sizeable posteriors to start with.

Nadia said: 'Our bottoms were already fatty. We always had bottom - it was never a difficulty to have bottom, but six months ago we did a fat transfer with a really good doctor in Columbia and it has given us a positively perfect one.

'We did the fat transfer because we are vain. We are vain women and the more surgery you have the more you want.'

Dana claims they were blessed with their curvy bodies due to their Latin and Brazilian blood making it easy for them to keep their bottoms well-toned

Dana added: 'We were blessed with having a curvy body because of Latin and Brazilian blood, So it's easy for us to keep the bottom well-toned.'

The twins claim being seen as sexual objects by men is in fact a 'blessing', although they also want to convey a positive image for women too. 

Nadia said: 'At the beginning I felt bad, like I was a sexual object for men but one day I saw it from the other side and thought if the men were not like this I wouldn't have a job.

Working out: The sisters say they now see the fact they are viewed as sexual objects by men as a 'blessing'

'Now I see it as a blessing and to be honest I am thankful to them – it is a positive thing.

'Even if people don't believe it, our idea is also to help women be able to lift their self-esteem and to give them a hand too. We can give tips to other women.'

Yet not everyone online is a fan and the twins say they have received abusive comments.

Nadia said: 'We have had problems with 'haters' lots of times. A lot of the time without knowing you they say you don't have brains.

'The envy exists – it bothers them that we are superficial but because of that we live in Miami beach and we are happy. 

Dana added: 'We feel very secure about who we are as people. We are upright citizens and clever women.

The twins say that they still keep up a private life outside of taking hundreds of pictures for their business

'One thing is what we show in Instagram and another is our private and personal life. This is a business - our image is a business. Our body is a work company like any other.'

Currently both Dana and Nadia want to maintain the amount of money they make for a further six months while they wait for a big project.

They say they know their image 'isn't going to last forever' so plan to expand their business as well as their bottoms.  

Nadia said: 'We'll keep modelling while we can because this is what we like to do and we know we also have talent.'
