The Sun's "picture exclusive," titled "Dirty Harry," shows the drunk-looking princes during a night out with pals. Word from Clarence House is that the photos are three years old.
The newspaper is graced with a shot of Prince Harry, 21, grabbing the breast of close pal, Natalie Pinkham. The politics graduate, according The Sun, has dated England cricket player Kevin Pietersen and England rugby star Matt Dawson.
While the story on the Sun's Web site does not say when the photos were taken, MediaGuardian.co.uk reported the Clarence House rebuttal today on its Web site.
Paddy Haverson, Prince Charles' communications secretary, told MediaGuardian.co.uk that the shots were taken at the nightclub Purple in September 2003, before Prince Harry began dating his current girlfriend Chelsy Davy.
The Sun later defended the authenticity of the photos to MediaGuardian.co.uk and said that "Clarence House have informed us they have concerns over precisely when and in which nightclub the pictures were taken and we are discussing these matters with them."
The Sun's cover shot shows a red-faced Prince William, 24, chatting to someone in the background while Harry kisses Pinkham's cheek and grabs her breast.
"Harry was really going for it," one witness told The Sun. "He had been downing drink all night and was touchy-feely with everyone — especially Natalie. He had his hands all over her and was kissing her on the face. At one point he reached his arm around her and gave her a proper grope on her breast."
"She was very shocked but didn't seem to mind in the slightest. I don't suppose it's every day an heir to the throne feels you up," the witness said.
