Celine Dion and her son at the Grammys

Celine Dion wowed fans at the 66th Grammy Awards on Sunday night in a rare appearance since she was diagnosed with Stiff Person Syndrome more than a year ago. The Quebec songstress surprised attendees when she came on stage to present the Album of the Year award — won by Taylor Swift. Dion, 55, dazzled the stage in a pink Valentino gown, paired with diamond jewelry and a honey-coloured long coat.
