Miley Cyrus was overcome with emotion while performing at the Super Bowl LV Tik Tok Tailgate concert. The 28-year-old singer broke down in tears during Wrecking Ball, which was written about her ex husband Chris Hemsworth, during the gig on Sunday afternoon.

It all started in smiles as Miley took to the stage in a black and purpled cheerleading uniform, which had "FTW" emblazoned across it.

She began her set with a take on Toni Basil's cheerleading inspired Hey Mickey, with the singer changing the lyrics to "Hey Miley".

The singer was joined on stage by 80s rocker Billy Idol, performing his 1982 hit White Wedding as well as Night Crawling.

Miley paid tribute to her godmother Dolly Parton by covering her hit Jolene but after a spectacular performance, Miley found herself struggling to keep on top of her emotions when singing Wrecking Ball.

Emotions ran high during the performance by Miley Cyrus.

During the performance, Miley stopped singing as she held her head down. As she wiped away tears, she told the audience: "Singing that song, Wrecking Ball, about feeling completely broken and shattered... everyone's suffering is different, even everyone's threshold of pain.

"I wear a lot of glitter and I wear a lot of armour, and I also wear my heart on my sleeve, and it gets broken a lot."

Miley finished with an emotional performance of her hit The Climb.
