Miley Cyrus breaks down on stage during Wrecking Ball performance

Miley Cyrus gave an emotional performance of her hit Wrecking Ball at the iHeart Radio Music Festival on Saturday in Las Vegas.

The singer had tears on her face while performing the song.

The 20-year-old sported some very edgy outfits at the event and performed her now famous twerking dance for the crowd.

Earlier this week Miley and Liam announced they were calling off their engagement after four years together.

The Hunger Games actor was seen kissing singer/actress Eiza González not long after that.
