Page Six reports the Hunger Games star, 24, was heard saying he and Miley would "always be best friends" and that they had "an instantaneous and powerful connection."
"Liam kept raving about how amazing she was, how much they clicked and understood everything about each other," the source added. "He also said they bought a lot of furniture but he had to leave it behind when they broke up and he got his new place, which was furnished."
Hemsworth and Cyrus ended their engagement after three years together in September 2013. After apparently dissing her ex during a concert in May, Cyrus took to Twitter to tell fans she wasn't talking about Hemsworth when she spoke of a "mother [expletive] that broke [her] heart."
"I never want hateful things being said about those I care about," she tweeted at the time. "I was just tooooo turnttttt up."
