Celine Dion honors René Angélil on their 30th wedding anniversary: 'You are everything for us'

Celine Dion is celebrating what would have been her 30th wedding anniversary with her late husband René Angélil.

The "My Heart Will Go On" singer, 56, took to Instagram on Dec. 17 to mark the day 30 years prior that she and Angélil said "I do" in an extravagant 1994 wedding in Montreal, Canada, sharing a heartfelt message.

"You still fill our hearts, every day. You are everything for us. We miss you so much," she wrote. "Happy 30th anniversary, mon amour!"

Dion signed the post not just from her, but from the three sons she shared with Angélil as well, René-Charles, 23, and twins Nelson and Eddy, 14.

Angélil, who also served as Dion's longtime manager, died in January 2016 after a yearslong battle with throat cancer. He was 73.

Dion opened up about her life and career in the documentary "I Am: Celine Dion," which was released in June. In it, she also detailed her battle with stiff-person syndrome, a rare autoimmune neurological disorder.
