Miley Cyrus is being blamed for the break-up between her Last Song co-star Liam Hemsworth and Laura Griffin -- at least, that's the reason for the breakup in Laura's mind.
He was my boyfriend and my best friend. There is no other reason why we would have broken up. It's Miley Cyrus! How can I compete?"
Miley has straight up denied that they're a couple, but she Tweets all the time about them hanging out, including the other night when she decided to "stay in to have sushi with Liam :)"
