Henessy was born on November 15, 1989 in Komsomolsk-on-Amur, Khabarovsk Krai, former USSR, Russia. At birth, the girl and future star, originally from Russia, who received the AVN Awards, was named Alina Eremenko. After the beauty graduated from school, she moved to St. Petersburg, where she successfully graduated from the university. When she turned 19, she started a career in porn and at the time of 2020 continues to act in adult films, living in Budapest, Hungary. The year 2008 for the girl was the moment when everything changed, because now she began to get not only pleasure from sex, but also money. Hennessy started her career as an actress, acting in scenes of lesbian sex only, but soon it was not enough for her. Then the girl became interested not only in traditional, but also anal, as well as group sex and even with elements of BDSM. In 2014, the actress returned to her roots and continued to act in porn only in scenes with lesbian sex, as she planned to devote more time to agency activities and try herself as a family person. In 2017, Alina, whose height is 160 centimeters and weight 52 kilograms, became the face of a bookmaker called "Leon".
