Demi Lovato on a gynaecologist asking for her autograph: 'You've seen my vagina!'

It's all about vaginas this week for Demi Lovato after confessing that a gynaecologist once asked for an autograph in the middle of an examination. Ewww.

The singer spoke to New Zealand radio station ZM about the doc's bizarre request. Check out her horror above. Also, isn't it all about the celeb selfie now anyway?

It's the second time this week Demi's made nether region headlines. On Thursday, tattoo artist Ashley McMullen slammed the star for covering-up a "vagina" tattoo.

Just in case you missed it, it's a pair of lips on her wrist – not on actual lady garden – which she turned into a rose.

When she posted the snap on Instagram, a certain Ashley lost it: "You pissed all over our toilet seat and you made a fool of yourself.

"What a shame that people look up to you. The tattoo you covered it with kinda sucks too. Looks like you might forever be a goon. #demilovato #scumbag #turd #claimstobesober #drankallthebeer #peepeetoiletseat #yousuck."

We have a feeling the hashtag turd is going to catch on. Anyway, we digress. Then Demi hit back with an epic smack down.

The main gist? Well, Demi said: "Maybe next time you should wait for the person to get your tattoo sober so they would actually remember getting the tattoo in the first place."

We wonder if the gyno got the same dressing down?
