Keyra Augustina or Keyra Agustina is the pseudonym of an Argentinian woman, famous for photographs and videos of herself circulating on the Internet. Keyra Augustina is best known as "Perfect Ass" girl. Her pictures are circulating the internet and she's caused a great deal sensationalism because of her unique assett. Most of her pictures show her beautiful butt, with her face hidden in the dark background. Keyra has been approached by several famous magazines such as Playboy and Penthouse, but unfortunately for her fans, she rejected the offers. However, she posed for Maxim magazine.


The name Keyra Augustina is believed to come from the aliases 'Keyra' and 'Agus', which she used to post on websites such as Supertangas.com and Foro Argentino de Amateurs. Wishing to keep her online activities from her family and friends, she seldom showed her face and preferred to focus on her buttocks. Her amateur photos and videos — which show her in various degrees of undress and provocative demeanor — were shot in her own room, using only a webcam.


She started to gain worldwide fame and recognition as her photos were widely downloaded and distributed on the Internet. Several people — including Howard Stern — have named her the "Best Ass on the Internet" and "Perfect Ass of the Year".


In June 2005, Maxim Argentina featured a 9-page photo spread with her. Later she appeared again in the August issue of Maxim US. This happened after a sort of "exclusive contract" Keyra had with Supertangas, thus the owners of the site alleged that these shots were fake, claiming that her face never appeared in the shots, but forgetting that themselves used to manipulate her Supertangas.com pictures to erase or simply cut her face off the pictures, because the model didn't want to be recognized by her family, friends or boyfriend. Who is Keyra?


Little is known about the true identity of the woman that calls herself 'Keyra'. Most sources agree that she is an Argentinian college student between 19 and 21 years of age. While Maxim Argentina referred to her as 'Mirna Lavagna, the illegitimate daughter of the Argentinian minister in Guatemala', it has since been proven that Mirna Lavagna is indeed an entirely different model. Others have stated that her true name could be Julieta Machado, Julieta Solecita, or Julieta Cordoba.
