People have been stunned to discover Apple is automatically tagging any iPhone photos that feature a bra into “brassiere” album.

This was news to many who only found out when one Twitter user posted a warning to other women.

“ATTENTION ALL GIRLS ALL GIRLS!!! Go to your photos and type in the ‘Brassiere’ why are apple saving these and made it a folder!!?!!?” @ellieeewbu tweeted yesterday.

In June last year a massive list was published of the thousands of different objects and scenes the Apple Photos app automatically recognises.
