The music icon paid tribute to the love of her life on January 16 during a performance at her Las Vegas residency show at Caesars Palace. It would have been René's 77th birthday.
Heartbreakingly so, January 16, also happens to be the death anniversary of Celine's older brother, Daniel Dion, who passed away just two days after her husband at age 59, from brain, throat and tongue cancer.
While the "My Heart Will Go On" singer stood on stage, she asked her fans to sing along with her while she performed a rendition of "You’re the Voice" (originally sung by John Farnham), dedicating the song to her beloved.
"This is the greatest gift that I can offer him for his birthday," the 50-year-old told the sold-out crowd. "What he loved the most in the world is the fans, the music and to see me perform for you."
Celine then asked the audience if they were "ready to sing the song for Rene" before she began singing the chorus of the loving song, which she concluded by blowing a kiss saying, "Happy birthday, my love."
René, who managed the pop icon's career since she was just 12-years-old, passed away of a heart attack at the age of 73 after a long battle with throat cancer.
The couple was married for 22 years before he left behind Celine and their three kids, Rene-Charles, 17, and 8-year-old twins Nelson and Eddy. René also had three additional children from his past marriages, Patrick, 50, Jean-Pierre, 41, and Anne-Marie, 41.
