The older brother of Cyrus's fiance Liam Hemsworth said that he has been too busy shooting "Thor: The Dark World" to see the singer's controversial appearance, reported E! Online.
"I haven't seen it. I've been in Kuala Lumpur two weeks ago, then Jakarta, then Hong Kong and Toronto now," he said.
The actor added that his time off is spent with his wife Elsa Pataky and their 16-month-old daughter India Rose, who he revealed is getting better and better at walking.
"The breaks I get, they're with my family. There's not much surfing the net at the moment," the "Rush" star added.
