Liam Hemsworth breaks silence after Miley Cyrus split, Kaitlynn Carter hookup

Liam Hemsworth broke his silence following his separation from Miley Cyrus over the weekend — but the Australian actor didn't say much.

The 29-year-old actor was out with big brother Chris and the "Thor" star's three children on Monday when The Daily Mail Australia approached him asking about the separation.

"You don't understand what it's like," he replied. "I don't want to talk about it, mate."

Like the mountain I am standing on top of, which was once under water [sic], connected with Africa, change is inevitable.
