The 'Price Tag' hitmaker recently uploaded a series of snaps showing off her figure on the social-networking sites Twitter and Instagram, but was shocked by a flurry of negative comments about her chest.
She has now taken to the micro-blogging website to call on her female fans to ignore comments criticising their looks, reported Contactmusic.
"So I'm seeing this weird debate on my pictures and people saying you have small breasts. Yes I do and I have very long legs and a small waist and small shoulders and size 6 feet! And I am proud of what I have! All girls should embrace what makes them unique. Stop being so negative about each other! Be proud," she wrote.
