30-year-old twins from Argentina Nadia and Dana Bruna make about $30,000 a month thanks to their surgically enhanced butts. They post about 150 selfies of their posteriors they call "belfies" which helped them to amass over 1M followers on Instagram. The money they earn make it possible for them to sustain a life of luxury. The "belfie queens" plan on expanding their business as well as their bottoms. For now their behinds measure 102cm each.
