Celine Dion and her son at the opening ceremony of the film

Celine Dion wiped away tears as she introduced her new documentary chronicling her battle with Stiff Person Syndrome, I Am: Celine Dion. An emotional Dion was handed a tissue by her son René-Charles Angélil as she delivered a speech on stage during a screening of her new film at New York City’s Alice Tully Hall on Monday.   Tears were visible as Celine told the audience at the close of her remarks: ‘Thank you to all of you from the bottom of my heart, for being part of my journey. ‘This movie is my love letter to each of you. I hope to see you all again very, very soon,’ she said, prompting the audience to erupt in cheers and applause.
