The British royal hit headlines last week when French magazine Closer ran pictures showing her stripping off during a recent break in Provence with her husband Prince William.
The couple subsequently took legal action over the furore and won an injunction, banning Closer editors from publishing any more of the pictures.
Australian pop star Minogue has now thrown her support behind the duchess and condemned the photographer who took the pictures as a "peeping Tom".
She tells Sky News: "It's always crossing the line, if you're on private property you should be able to do whatever you like - that should be everyone's right. For me, that story and any like it, I don't see why that's not considered to be like a peeping Tom and that's creepy, it's awful."
