It looks like Liam Hemsworth's split from Miley Cyrus might not be as amicable as it looks. On Monday, the actor, who has been in Australia nursing his broken heart at the palatial home of his big brother, Chris, told Daily Mail Australia, “You don’t understand what it’s like," when asked about the breakup. "I don’t want to talk about it, mate.” To rub salt in the wound, Cyrus has been canoodling with Kaitlynn Carter, who happens to be the ex of Brody Jenner. Cyrus and Hemsworth announced their intention to part ways over the weekend.
