Miley Cyrus and Liam Hemsworth appear to be happy with one another during their regular outings in Southern California, but according to a new report, the re-engaged couple may not make it down the aisle as planned.

While the couple stays silent about their future plans, including their potentially upcoming wedding, a source has suggested that Cyrus and Hemsworth are on the rocks as the singer films the 11th season of NBC's The Voice.

On October 12, the Hollywood Life shared a report from Life & Style which stated that Cyrus had not only called of her engagement to Hemsworth in recent weeks, but also escaped Los Angeles and headed to Tennessee for some private time with her family.

“Miley said she didn’t feel like their relationship was strong enough to continue with the [wedding] plans,” a source told the magazine. “Liam was completely devastated and still is. He won’t talk to anyone about it and doesn’t want to believe it’s real.”

Cyrus is “rethinking” their entire relationship, another insider said. “She’s told friends and family that she doesn’t think their personalities mesh anymore. She’s a free spirit and full of energy and she’s starting to find Liam a little boring."

According to the report, Cyrus and Hemsworth have been at odds recently due to her wild ways and smoking habit. In fact, a fight about Cyrus' smoking habit was reportedly what led Cyrus to call off her engagement and wedding. As the source revealed, Cyrus was screaming at Hemsworth during their spat and told him he was holding her back from who she really is.

While Cyrus is reportedly against the idea of getting married to Hemsworth after their fight, the actor is said to be staying positive and hoping that they can work through their issues just as they did at the end of last year when they reunited after calling off their engagement two years prior.

 “Liam still hopes they can work things out,” a source said. “He isn’t ready for this to be over.”
