When Miley Cyrus channeled her inner Beyoncé and put a ring on longtime boyfriend Liam Hemsworth‘s finger, it was supposed to be a sign of their commitment to each other. There was just one small problem: the Australian actor refused to wear it.

That did not sit well with Miley, 24, and sources reveal exclusively to Life & Style that the piece of jewelry became the subject of a nasty shouting match. “She pushed him and pushed him to wear the ring,” the insider says, “and she finally lost her temper and was screaming at him furiously. The fight was one of the worst they’ve ever had.”

The former Disney star was so mad she actually threw her phone to the ground and smashed it. “She refused to talk to him for almost two days after that,” the source adds.

Liam, 27, has since apologized and agreed to wear the promise ring. He was recently spotted out with the hardware on that finger, prompting wedding rumors. However, the couple is not walking down the aisle anytime soon.

“He wears that ring as more of a ‘promise’ to Miley, but they are not officially married,” a source told E! News. “The only thing that is missing is the legal piece of paper. The pair is not focused on planning a wedding at this time. They are more focused on making their love as strong as possible.”

We don’t see how Miley can be that upset at the Hunger Games star, seeing as she has publicly dissed her engagement ring multiple times. “This is really weird, because this is like real jewelry and most of my jewelry is made out of gummy bears and cotton candy … they don’t look that good together because they kind of mix up,” she told Ellen Degeneres. “So sometimes I replace it with an actual unicorn or a Looney Tune. And [Liam’s] kind of like, ‘What’s going on?’ I am like, ‘This isn’t really my aesthetic, but I’ll wear it because you love me.’”

Miley and Liam, who have been engaged on and off since 2012, both agree the fight has strengthened their relationship. “Things have turned around lately,” the source tells Life & Style. “Miley and Liam are so much happier now.”
