The 47-year-old broke down in tears during her performance, her first since the passing of her husband René Angélil back in January.
Céline honored her late husband during her performance with a written message, a video montage and an emotional speech to the crowd in which she said, "We will always be one. You know, I might not hear his voice yet, but I talk to him, I think of him all the time. I feel and I know he hears me."
