Miley Cyrus cares about the "promise" she has made to fiance Liam Hemsworth more than their wedding.

The actress-and-singer got engaged to the actor in May and she insists they are in no rush to walk down the aisle and instead wanted to make a commitment to one another.

In an interview with Marie Claire magazine, she said: "Life is too short not to be with the person you want to be with. I don't really care about the wedding or the piece of paper as much as I do the promise we've made to each other. And we want to have a long engagement."

Liam, 22, presented Miley, 19, with a vintage engagement ring when he popped the question and the former 'Hannah Montana' star is thrilled with the band he picked out.

She explained: "I had no input. We'd been kind of talking about [getting engaged], and I saw something like it online at one point and thought it was really pretty, but I usually wear rose gold. I just love that it's old and has a story. And I'm happy because it doesn't look like anything else I wear."

However, it seems Miley has competition for Liam's affection - her dog Ziggy.

The mutt is besotted with the Australian hunk and spends all her time snuggling up to Liam when she isn't eating her owner's jewellery.
