Demi Lovato stunned by gynaecologist's autograph request

Demi Lovato was once stunned by a gynecologist who asked her for an autograph while studying her vagina.

The singer admits she has been asked to sign her name in some strange places, but a bold medic really surprised her with a request.

She says, "There have been so many uncomfortable and actually violating moments when like, I've been at the gynecologist and the doctor's like, 'Can I have an autograph for my daughter?'

"I'm like, 'F** you...! What the hell is wrong with you?'"

The Skyscraper hitmaker has also had a strange encounter with a cosmetologist - while she was getting her bikini area lasered.

She explains, "Someone will say, 'My such and such is a huge fan' and it's like, 'Great, you can now tell them you've seen my vagina!"
