Family getting involved in a relationship is never a good thing!

Liam Hemsworth's brothers Chris and Luke don't support their sibling getting married to fiancee Miley Cyrus, and they are trying their best to stop it!

The Hunger Games star's family actually staged a relationship intervention in April, and it seems their pleas were taken seriously, as the couple recently pushed back their wedding date indefinitely.

"They want him to end the romance for good," a source tells Us Weekly.

Although they haven't officially split, the pair has been spending lots of time apart in recent months. "Liam is pulling away," the source adds.

We bet the Aussie hunk and Miss Miley never make it down the aisle!
