After a previously unseen photo of the late Princess Diana popped up in a report about an auction, the mystery man pictured next to her has been identified.

The photo is owned by Eric Caren of Caren Archive, who is putting the photo up for auction later this month. The photo reportedly shows a young Diana before she married into the royal family. The words "not to be published" written in black grease pencil appear written across the photo. The image was previously owned by the former British Newspaper the Daily Mirror.

Diana is seen with a man who has been identified by Adam Russell, according to ABC News. Russell was a student at Oxford University at the time the photo was taken and he is now a deer farmer in Dorset, England. Russell is also the great-grandson of former Prime Minister Stanley Baldwin.

ABC News contacted Russell, who confirmed it was him in the photo. He refused to say anything else.

According to royal biographer Andrew Morton's book "Diana, Her True Story -- In Her Own Words," Diana was invited to a family holiday of her friend Mary-Ann Stewart-Richardson in the French Alps. Diana fell on the ski slopes and tore tendons in her left ankle. She and Russell spent time together there as they were both recovering from their injuries.

Morton claims, according to the news site, that Russell "always liked Diana but nothing ever happened, in part because he never expressed his desire for her."

Diana, mother of the UK's Princes William and Harry and one of the most famous contemporary royal icons, was dating businessman Dodi al-Fayed when the two were killed in a car crash in Paris in August 1997 after being chased by celebrity photographers. The princess' televised funeral was watched by more than 2.5 billion people.
