River Delfín Canomanuel Viiperi (born 4 August 1991 in Ibiza, Spain) is a Spanish male model. He has been in several advertising campaigns, including those for American Eagle, Bershka, Calvin Klein, Armani Exchange and Versace for H&M.
River was born in Ibiza to a Spanish father and a Finnish mother. River's mother, Riitta Viiperi, was also a model. She saw potential in him and eventually introduced him to the world of modeling. It was not hard to convince him since he hated school, though his parents insisted he keep studying, at least until high school and soon after followed in his mother's footsteps. Though still very young, his modeling career took off very quickly and he became popular in a very short time: doing countless editorials; gracing the covers of Winq, Surface, Guapo, and Coitus; and walking for Calvin Klein shows. River has an older sister named Luna. His hobbies include soccer, swimming and martial arts. He has his own blog called Never Back Down in which he denies common myths about the world of the male model and describes his experiences living with his roommates in their models' flat.
