Chris Hemsworth is reportedly worried that Miley Cyrus will break Liam Hemsworth's heart. The couple reunited recently after calling off their engagement in 2013.

According to NW magazine, the Thor actor wants his brother to review his relationship with the former Disney star. A source said: "She's dropping all these hints that she's not marriage material but he's not catching on at all."

"While Miley may love him, if they don't get on the same page soon, it'll only end in heartbreak for him," the insider added. "He really wants to make it official."

"She's never saying that they're going great or how happy he makes her. Instead, it's all about how she doesn't like this and isn't a fan of that," the source continued.

Meanwhile, Cyrus had opened up about her engagement ring from Liam. During an appearance on The Ellen Show, Cyrus talked about the ring on her finger. She said: "This is really weird because this is like real jewelry and most of my jewelry is made out of gummy bears and cotton candy and they don't look that good together because they kind of mix up so sometimes I replace it with an actual unicorn or a Looney Tune. And he's kind of like what's going on? I am like this isn't really my aesthetic but I'll wear it because you [Liam] love me."
