Miley Cyrus' personal woes are starting to get to her.
While performing at the iHeartRadio Music Festival in Las Vegas on Friday, the 20-year-old songstress broke down while performing [see video below] her latest hit "Wrecking Ball."

Just like in her video, Miley began to cry and even got choked up as she sang the sad lyrics, which are about her relationship with Liam Hemsworth. The duo called off their 15-month engagement last week.
According to eyewitnesses, the former Disney star ran to her mother and hugged her after the number. Life & Style can now reveal that Miley's breakdown continued backstage.
"She really lost it," an eyewitness tells Life & Style. "She was hysterical crying. There were a lot of tears."

After a few emotional moments, Miley took control of herself.
"She pulled herself together quickly and was like, 'Let's go party and get crazy,'" the onlooker shares.
In recent weeks, the singer has caused a lot of controversy. Weeks after her raunchy VMA performance on Aug. 25, she debuted the scandalous video for "Wrecking Ball" — in which she's seen riding a wrecking ball naked and licking a sledgehammer.
But her inappropriate behavior — and clothing — continued during her iHeartRadio performance.
"She was wearing a white lace-up bustier top and white booty shorts," an eyewitness at the concert tells Life & Style. "She was dancing on stage with little people, who wore denim booty shorts and twerked constantly, and people dressed in blow-up mushrooms and rainbows. She danced provocatively with them, stuck her tongue out a couple of times and grabbed her crotch a lot."
Before singing a new track, "Look What They've Done to My Song," Miley, who wasn't wearing her engagement ring, said she knows she's been doing things that have been getting her attention and in trouble.
"She explained that she's just doing what it's her heart — and what her soul is telling her to do," notes the observer.
Miley performed again at the festival and in even more revealing attire — a completely sheer white ensemble with big white furry sleeves and black nipple pasties.
