The royal was said to have won the vote of his new girlfriend and TV presenter Caroline Flack, who formed a part of the panel for the women's magazine, Company.
"Caroline did seem a bit distracted during the voting. Now we know why," the Daily Express quoted Victoria White, the magazine's editor, as saying.
White added: "Our readers love Prince Harry. He's posh and polite, yet rugged, fun and very down-to-earth."
Caroline, 28, was previously snapped with Harry, 24, after a night out in London, and the two were reported to be besotted with each other.
The pair were allegedly drawing plans to go on holiday together in Cornwall later this year.
