Miley & Liam 'Hanging By A Thread' After Last Ditch Effort Sex Pact Fails

Miley Cyrus and Liam Hemsworth are trying to do damage control, RadarOnline.com has exclusively learned, as their romance hangs by a thread.

But their friends aren't fooled.

"The fact they're admitting their engagement is in limbo is proof they're not in a good place at all," a source confessed to RadarOnline.com. "Just six months ago they were making wedding arrangements and couldn't stop flaunting their love to the world. Now they're barely speaking."

As RadarOnline.com readers know, the lovebirds have called off their engagement for a second time and in order to get their love back in line the duo were amping up their sex life with a signed sex pact contract in a last-ditch effort to stay together.

"They pledge to increase the sexOpens a New Window. because she likes to get a little wild sometimes," a source previously told RadarOnline.com exclusively.

Cyrus, 25, has been stressed out over planning a massive celebrity wedding and is rethinking her commitment to the hunky Hunger Games actor, 28.

"She's deleted all her posts about Liam and it's more of a friendship while they figure things out," the source added.

The former Hannah Montana star has even moved out of the Malibu mansion that she once shared with Hemsworth, and back in with her mom and dad.

A last-ditch effort to sign a relationship contract, complete with stipulations on how much and what type of sex the couple can enjoy, has apparently had little help in solving their overreaching issues.
