Iman has paid tribute to her late husband David Bowie on what would have been their 25th wedding anniversary.

The model, 61, shared a touching black and white photograph of the couple kissing with her nearly half a million Instagram followers.

The image shows the pair under an umbrella in the rain, with Bowie pressing his lips against Iman's forehead.

The caption reads: "I would walk forever, just to be in your arms again."Iman added the hashtag "#BowieForever".

The Black Star singer died aged 69 in January last year following a battle with cancer.

He and Iman actually tied the knot in Switzerland in April 1992, but held a church ceremony on June 6 of that year in Italy.

They had one daughter, Alexandria.

Iman shared a picture of Bowie with Alexandria as a baby on Instagram when she celebrated her 16th birthday last year.
