Miley Cyrus Went “Ballistic” on Liam Hemsworth After He Confirmed They’re Not Engaged (EXCLUSIVE)

Trouble in paradise!

After making their first public appearance at the The Huntsman premiere since rekindling their romance, Miley Cyrus and Liam Hemsworth are on the outs — again.

A source tells In Touch, "Just as Miley and Liam were starting to plan their wedding, he had a change of heart."

Cyrus' insecurities could be to blame for their falling out, as _ In Touch_ previously reported that the couple's relationship was barely hanging on because of her fear he would leave her at the altar.

"He still wants to be with Miley, but isn't sure about a lifelong commitment," the source said.

Adding fuel to the fire could have been when Liam, 26, recently confirmed to an Australian magazine that he is "not engaged." This came just days after the 23-year-old singer was spotted wearing the 3.5-carat ring engagement he gave her back in 2012.
