The 23-year-old actor's parents, Leonie and Craig, and his older brothers Chris and Luke, who staged an intervention in a bid to get him to end his relationship in April, have been supporting him since his split from the 'Wrecking Ball' hitmaker, reported Hollywood Life.
"This is the happiest they've seen Liam in a long time and they are supporting the break up. His family is thrilled that he has completely cut ties with his ex-fiancee," a source said.
Meanwhile, the Australian star, who was photographed kissing Mexican actress Eiza Gonzalez just one day after his split from Miley, was reportedly spotted partying in New York City hotspot Ainsworth Park.
