"I'm so sorry for crying," she said tearfully after being left speechless for almost a minute at the mic. "I want to be so strong for my family, and my kids and I didn't expect that."

"I don't want to cry in front of you, but you make me so happy," she said directly to her son. "Thank you."

After asking her son to stand next to her throughout her acceptance speech, Dion continued sharing her emotional thanks to everyone she's worked with and loved throughout her life, everyone who has helped propel her to the icon status that she has earned.

"This is such a tremendous honor," she said. "Music has been my pasison since before I can almost remember. So many people have helped me get where I am today -- I cannot name them all, obviously, but I hope they recognize themselves."

She then looked up into the stands and thanked her "fans for traveling through music with me through good and bad times."

Her voice wavered again when it became time to address her family and her late husband's tragic absence on her big night.

"[I want to thank] my family: My mom who wrote my first song, my children and, most importantly, my beloved husband, who I know will continue to watch over me from up above."

Before lifting up her award, Dion declared that "the show must go on!"
