On her Instagram, the supermodel shared a post that quoted Alfred Lord Tennyson. "If I had a flower for every time I thought of you," the quote reads, "I could walk through my garden forever."
She also shared a photo of Bowie performing, along with the hashtag "#BowieForever."
Bowie, who rose to fame in the '60s and was named the Greatest Rockstar Ever by Rolling Stone, died after a battle with cancer on January 10, 2016, just two days after his 69th birthday and the release of his final album Blackstar. The album would go on to win the British Album of the Year at the 2017 Brit Awards as well as five Grammy Awards.
Iman and Bowie married in 1992 after two years of dating. They share daughter Alexandria Jones, who also goes by Alexandria Bowie, 20.
In 2018, Iman revealed to Net-A-Porter's digital magazine PorterEdit that she has no interest in marrying again.
"I mentioned my husband the other day with someone, and they said to me: 'You mean your late husband?,'" Iman explained to the outlet. "I said, 'No, he is always going to be my husband.'"
"I do feel very lonely," she continued. "But do I want a relationship? I can't say never, but no, not now."
She echoed the statement in a 2021 interview with Harper's Bazaar, telling the magazine, "David is in our hearts and minds on a daily basis, for all of us. You know, this was my true love. My daughter once asked me if I would ever marry again and I said, 'never.'"
