The “Wrecking Ball” crooner and Hemsworth started dating in 2010. They announced their engagement in 2012, but called it quits in 2013. However, the pair reunited and became engaged for a second time in 2016.
The notoriously private couple last stepped out for a red carpet in March for the 2018 Academy Awards. The pair were spotted at multiple Oscar parties over the award show weekend, including Elton John AIDS Foundation Oscars Viewing Party.
