Closer France caused outrage after choosing to run long-lens photographs of the Duchess of Cambridge and her husband Prince William taken while on a private break in Provence.
Laurence Pieau, the editor of the publication, has now defended the decision, insisting that the "nice series" of photos "are full of joy" and describing the reaction to them as "disproportionate".
"One shouldn't dramatise these pictures," she told The AFP. "The reaction has been a little disproportionate.
"It is a young couple that has just been married. They are in love. They are beautiful. She is the princess of the 21st century.
"These are pictures that are full of joy. They are not degrading. Similarities have been drawn with the [nude] pictures of Prince Harry. They are not similar. These are not degrading."
Pieau went on to claim that the royal couple were "visible from the street" when they were photographed and claimed that Closer had seen pictures of them that were "more intimate".
She said: "Honestly I don't know of a single celebrity magazine in the world that would not have run these pictures had they had them. They wouldn't have hesitated two seconds before running. Once should not be hypocritical.
"I won't hide the fact that there are more intimate pictures that exist that we haven't published and will not publish. Probably other newspapers will choose to publish them, but that was not our choice".
St James's Palace has issued a statement on the pictures in which they compared the incident to the "worst excesses" of the paparazzi during the life of William's mother Princess Diana, who died in a Paris car crash in 1997 while being pursued by photographers.
