Celebrity photographer Chris Colls sparked rumours of a romance with his model muse when he started uploading nude pictures of Miranda onto his Instagram account.
The pair has been friends for years, with Miranda choosing Chris to shoot her for several big projects, including her recent book Treasure Yourself.
Chris split from his wife Fearne last year and is currently involved with model Alexandra Agoston.
Miranda announced she had ended her marriage to actor Orlando Bloom last week, after “months” of living apart.
The couple have one son, Flynn.
