The picture shows a large diamond ring on her engagement finger, whilst Cyrus further promoted a brand of nail polish. She wrote: 'I am soooo obsessed with @jennahipp nail foundations! It looks so chic and classic!" Take a look'. It is still unknown whether she and Liam Hemsworth have decided to tie the knot.
