Her first name comes from a song (Celine, sang by Hugues Aufray and written in 1966 by Vline Buggy) that her mother was singing while she was pregnant.

She grew up surrounded by music. In Le vieux Baril (The Old barrel), a piano-bar restaurant in her home town owned by her parents, the children were doing waitressing and singing for the clients. The family held regular jam sessions, with Adhemar (her father) playing accordion and Therese (her mother) playing violin. The family was spending their free time singing and playing different musical instruments, as everyone in this family is musician. Celine plays the piano.

She first stood on a table to sing a Ginette Reno song at the age of 5! At five hand a half years (On August 18th, 1973), she sang the song "Du fil, des aiguilles et du coton" (some thread, some needles and some cotton) at her brother's (Michel) marriage. Soon, many town's people were planning their evenings by going to hear "La p'tite quebecoise" (the little quebecer).

At the age of 12, Celine announced to her mother that she couldn't imagine doing any other career but the one of a singer. Therese, acknowledging her daughter's talent, wrote a song for her, Ce n'etait qu'un rêve (It was only a dream). It was recorded on a demo tape and sent to Rene Angelil, a well known manager in Montreal. After he heard the tape, he asked to hear her live at his office.

He was impressed and touched by the strength and the control of her young voice. He cried listening to her voice, and he agreed to work with her. He had to mortgage his house in order to pay for the production of her first two albums! Today, Rene still continues to manage Celine's career; consequently, he has led her to the top of the charts all over the world.

In December '90, she and other associates, have launched the Nickel's restaurants.

On May 2nd, '93, her niece Karine (daughter of her sister Liette) died at age 16 from cystic fibrosis. Celine is the spokesperson of the Canadian Cystic Fibrosis Foundation for many years, she does so in memory of Karine now.

In December 1994, she married Rene Angelil her manager who is 26 years her senior. It was, of course, the biggest event of the year among the jetset in Canada.
