The breakup rumors are true--Miley Cyrus and her boyfriend of over a year, Liam Hemsworth, have called it quits, PEOPLE reports. His rep confirmed to the magazine that the 'Last Song' co-stars were indeed no longer dating. Gossip Cop first reported the news earlier today.

It's been speculated for months that the pair were no longer together--and in June, Cyrus even took to her website to assure fans that they were still together and "so happy." But something must have changed over the summer.

Earlier this year, in happier times for the couple, the Disney star, 17, told PEOPLE that Hemsworth was one of a kind. "I'm not really a big lovey person. I'm not, like, mushy. [But] Liam was the first person that made me want to be in a real relationship," she said.

The 20-year-old Australian actor also spoke highly of his beau at the time, saying their relationship was "pretty serious" and that he liked her "big heart."
