It's been the couple's worst kept secret that they're engagement has hit rocky water.  Now it seems Miley Cyrus and Liam Hemsworth are officially postponing their nuptials.

One source close to the couple tells "They want to figure out their life together before they get married."  Reportedly the fiances originally wanted to tie the knot this summer.

"They're still engaged and living together," adds the source. "They just realized that there is no rush with the wedding and that it's better that they wait a bit."

Rumors of a breakup ran rampant after reports surfaced that Miley was roaming around sans her engagement ring last month, and Hemsworth jetted off to his native Australia for a little alone time.

In a recent interview with ABC's Nightline, Miley's dad Billy Ray Cyrus said he was unsure if his daughter and the actor would ever get hitched.
