Céline Dion's beloved husband, René Angélil, who also discovered her and managed her career, died four years ago Tuesday, Jan. 14, and the star has posted a touching tribute to him on Instagram.

Next to a photo of a smiling Angélil cradling a sleeping dog, Dion wrote, in both English and French, "There is not a day that goes by without me thinking about your beautiful smile. We miss you, thank you for watching over us my love. I love you. Céline xx."

Angélil first met Dion when she was 12 years old and they married in 1994. They had three children: René-Charles, 18, and twins Nelson and Eddy, 9.

In 1999, Angélil was diagnosed with throat cancer; he died of the disease in 2016 at age 73.

Since her husband's death, Dion, 51, has taken over as the president of her management and production companies. Her No. 1 album, "Courage," features songs largely inspired by how she's moved on with her life, and she's currently on a world tour promoting it.

And while her romantic life has been a subject of great speculation, Dion said recently, "If I do [find love again], that will be great. If I don't, that will be great because I'm still in love [with Angélil]."
