British pop star Jessie J has urged young girls to be proud of their assets after her own body was criticised online.

The Price Tag hitmaker recently uploaded a series of snaps showing off her figure on social networking sites Twitter and Instagram, but was shocked by a flurry of negative comments about her small chest.

She has now taken to the microblogging website to call on her female fans to ignore comments criticising their looks and focus on their best qualities instead.

The singer writes, "So I'm seeing this weird debate on my pictures and people saying 'you have small boobs'. 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! Boobs or no boobs!"
