5. MILEY CYRUS AND LIAM HEMSWORTH

After the longtime couple announced their split in August 2019, things got a bit, er, messy … to say the least. Miley quickly moved on with MTV reality star while Liam was left heartbroken. “Liam hit the roof when photos emerged of Kait and Miley hooking up,” a source exclusively told In Touch at the time. “It was the straw that broke the camel’s back.”

Since then, Liam officially filed for divorce and Miley and Kaitlyn split. The pop star moved on with fellow singer-songwriter, but the pair split in August 2020.
