Actor Liam Hemsworth is miffed with fiance Miley Cyrus and the reason is as good as anybody's guess.

Apparently, he is so tired with her weird antics that he has decided to call of their relationship now.

Things went uglier between the two after Cyrus hit the headlines for twerking and flirting with singer Robin Thicke during MTV Video Music Awards.

"The VMAs is the straw that will break him. He wants out of the relationship," a Life and Style magazine quoted a source as saying.

Hemsworth`s family and friends have also advised him against the relationship.

"All of his family and management are begging him to break it off and publicly move on," said a source.
