Miley Cyrus gave an emotional performance during her appearance at the iHeartRadio Music Festival in Las Vegas yesterday (September 21).

Taking to the stage at the MGM Grand Garden Arena in an all-white ensemble of a crop top and hotpants, Cyrus kicked off her set with ‘We Can’t Stop’.

During the show a pink bra was thrown at Miley from the crowd which the former Disney child star then chucked back into the audience.

However Cyrus’ delivery of her latest track ‘Wrecking Ball’ was far more sombre as she cried during the number and had tears rolling down her face.

‘Wrecking Ball’ recently gave the 20-year-old singer her first No. 1 single in the US.

Miley Cyrus’ new album ‘Bangerz’ will be released in the UK on October 7.
