Ekaterina Lisina, 29-year-old woman from Russia also broke the Guinness record for being the tallest female professional model with a height of 6 feet 8.77 inches.
Her left and right leg measure 132.8 cm and 132.2 centimetres respectively.
As required by the Guinness World Records guidelines, the measurements were taken by independent professionals - a seamstress and doctor - from the heel to the top of the hip.
Lisina said that she was bullied in school for her height and she wanted "to be an inspiration to girls who are not very confident."

She has now been working as a professional model for over a year.
