Cléa Gautier was born in Lyon (France) on October 25, 1990. After secondary school, she studied philosophy and psychology at the Institute of Psychology - PSYCHO - dependent on the University Lumière-Lyon-II. It was at this time that she decided to leave the family cocoon. She works as a charming model for various French publications, parades on various catwalks and exercises, for a time, as a Go-go dancer. It was during one of her exhibitions that she met Anthony Gaultier with whom she lived as a couple. The latter, after watching a few films featuring her as Offered to Others, suggests that she pursue a career in pornography. Cléa contacts the Jacquie et Michel studios for which she interprets, with mixed success, a small number of DVDs including her first interracial film. The beginnings are difficult because the competition is tough in the middle of pornography. In 2016, her companion sent some photographs of Cléa to producer Marc Dorcel who gave her the opportunity to start a career as an actress in pornographic films. She was then 26 years old. Her body, very supple and sculpted by many years of classical dance, allows her to conquer many fans.

Cléa Gaultier works for various European and American studios including Video Marc Dorcel, Brazzers, Reality Kings, New Sensations, Naughty America, Digital Playground, SexArt, Tushy, Girlfriends Films, Evil Angel, Private among others.

In 2017, Cléa recorded, together with Apolonia Lapiedra and Ella Hughes, a first interracial-themed DVD for Private entitled Pajama Party.
