Nikolett Pósán (born 10 March 1983), known by her stage name Niki Belucci, is a Hungarian DJ and former pornographic actress.
Born in Budapest, at young age, Belucci practiced gymnastics and won several medals in youth competitions, before stopping at the age of 15 years because of a serious injury. She later got a diploma in hotel management school and, at the age of 19 years, started working first as a nude model and later as a pornographic actress. Belucci eventually left the porn industry shortly after getting married. During her adult career, she starred in about thirty films.
Belucci started her career as a DJ in 2003, collaborating with two Hungarian DJs, Spigiboy and DJ Mozsó, and embarking on a tour called the "Orgasmic Tour" as a tribute to her adult career. During her musical career, she made a worldwide tour and released a mix-album and several singles. In 2010, she was the resident DJ of the Amnesia nightclub in Ibiza.
