The 20-year-old from Boston wrote and produced the song in which she tells us that whether you're a size 2 or not, 'every inch of you is perfect from the bottom to the top'.
The official video for the song has been released on Trainor's VEVO account. Take a look at it here.
And may we highly recommend this acoustic cover of 'All About That Bass' which we think is almost even better than the original version!
