Chris Hemsworth is reportedly worried that Miley Cyrus will leave his little brother Liam Hemsworth with a broken heart. The development comes after the Wrecking Ball hitmaker revealed that she is not ready to be a wife.

Speaking on the Ellen DeGeneres Show, the songstress had confirmed she and Liam are engaged, but also admitted that she does not like the diamond ring The Hunger Games actor proposed with as it is "too bling."

"I think young people have a different idea of partnering and [don't need] to have a legal document signed and dated," she during her chat with host Ellen. (Via Yahoo) "It's really sharing a life with someone and not about a legal paper. Even though I fought so hard for LGBTQ [marriage] rights. I don't really want to."

According to NW Magazine, the Thor actor is concerned that Cyrus is not "marriage material" although the 26-year-old actor is looking to settle down with the 23-year-old singer as soon as possible.

Liam's friends and family, including Chris, has told The Duel actor that "she's [Miley Cyrus] dropping all these hints that she's not marriage material but he's not catching on at all", a source told the magazine.

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

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

Cyrus and Liam started dating after meeting on the sets of their movie The Last Song in 2009 and got engaged in 2012. However, the two called off their engagement in 2013 only to reignite their romance in December 2015.
