Demi Lovato was asked by a gynaecologist for an autograph midway through her examination.
The Heart Attack pop star revealed her most "violating" moment was when she had her vagina studied by a women's health doctor who made the untimely request for her signature.
In an interview on New Zealand Radio Station ZM, Demi said: "There have been so many uncomfortable and actually violating moments when like, I've been at the gynaecologist and the doctor's like, "Can I have an autograph for my daughter?"
On being stunned by the request, she described her reaction as: "I'm like, 'f**k you! What the hell is wrong with you?"
It's not the first awkward fan encounter Demi has had while undergoing an intimate procedure.
