On the heels of her split with ex-fiance Liam Hemsworth, the 20-year-old singer had tears "rolling down her face" as she sang, after kicking off her performance on a lighter note with 'We Can't Stop', reported E Online.
Representatives for Hemsworth and Cyrus announced earlier this week that the couple had called off their engagement, and just a day later the "Hunger Games" star was snapped sharing a passionate kiss with Mexican singer-actress Eiza Gonzalez.
Cyrus hit the stage in a white crop top and hot pants combo, dancing around and twerking for the crowd.
