Chris Hemsworth "can't see" his brother Liam getting engaged to Miley Cyrus in the near future.

The Hunger Games actor has been dating the former Hannah Montana star on and off for almost three years and while it was recently rumored they were set to tie the knot, Chris says it's very unlikely as they're not ready.

"They're like 21 or something ... I can't see that happening. You have to ask him about his relationship," the Thor star said.

And it seems Liam, 22, agrees with his older brother as he recently said he was too young to wed 19-year-old Miley: "Marriage and kids are way in the future for me. I'm young. It's not really on my mind at the moment - marriage, kids or anything."
