The musician died two days after his 69th birthday in 2016.
The 63-year-old model took to Instagram on Tuesday to remember her husband on what would have been his 72nd birthday. Bowie died in 2016 -- just two days after his 69th birthday -- following a battle with liver cancer.
In the words-only post, Iman wrote, "My memory loves you. It asks about you all the time."
The emotional post comes one day after Iman shared a photo of herself and Bowie. In the pic, the musician is lovingly kissing his wife on the cheek as she flashes a glowing smile. "#BowieForever," she captioned the image.
“I will never remarry,” she shared. “I mentioned my husband the other day with someone, and they said to me: ‘You mean your late husband?’ I said, no, he is always going to be my husband.”
“I do feel very lonely. But do I want a relationship? I can’t say never, but no, not now,” she added.
In addition to their marriage, the couple also shared a daughter, 18-year-old Alexandria.
“She says I am overprotective,” Iman confessed of her daughter with Bowie, whom she calls Lexi. “But I told her, this can all wait, it isn’t going anywhere. Have a life that is private while you can, because one day soon it is going to be public, so enjoy this.”
