But try telling that to Laura Griffin.

The 19-year old Australian had to find out from her pals that boyfriend Liam Hemsworth had made out with Cyrus away from the cameras of the film they were shooting together, The Last Song.
Soon afterwards, he ended the relationship with Griffin. Coincidence? She clearly thinks not.

“He was my boyfriend and my best friend,” Laura told an Australian publication this week. “There is no other reason [other than Miley Cyrus] why we would have broken up.”

Over the last few days, Griffin has done something to which Cyrus can relate: post messages online. On her Facebook account, Laura’s moods have ranged from “total utter regret” to “depression of some sort.”

She couldn’t even muster up the enery to add a sad face at the end.

We hope this fling was worth it, Miley!

Now, based on multiple reports, it sounds like the Disney icon has been working up a sweat with the Australian actor – if you know what we mean!

We mean this: the pair has been spotted kissing… off camera!

Both The New York Daily News and People quote witnesses that say Cyrus and Hemsworth played an intense game of tonsil hockey at the Nashville airport on Wednesday.

In fact, actor Alex Emanuel was standing a few feet away and said the rumored couple was “full-on making out.” He told People:

“[Miley] jumped into his arms and threw her arms around his neck and kissed him and leaned back and he was dipping her. It was like a scene out of an old movie where the guy’s getting on a train and they’re saying their goodbyes.”
