Miley Cyrus was once left aghast after her beloved pet dog gobbled down her diamond jewelry. The former "Hannah Montana" star, who is engaged to actor Liam Hemsworth, admits her pooch Ziggy can be unruly - but even she was shocked when the canine raided her stash of jewels. Cyrus tells Marie Claire, "She's a stubborn little b**ch, that one. She doesn't listen to me. She's in love with Liam." "She loves me when he's gone, but she totally ate my diamonds on purpose. She was pooping them out all morning!"
