Miley Cyrus suffers technical problems at Bono's charity show

Miley Cyrus was reportedly lost for words during a performance of U2's One at Bono's charity show on Tuesday (01Dec15) when her teleprompter failed.

The pop singer was among the stars who turned out for the Irish rocker's gala concert in New York City to mark World AIDS Day (01Dec15), performing her own set before returning to the stage for the finale.

Miley teamed up with Bono, his bandmate The Edge, and British pop star Jessie J for a performance of classic U2 track One, but the Wrecking Ball star was left unable to join in because the lyrics were not being properly displayed on a screen in front of her.

The singer turned to Bono and pleaded "You got to help me... Nothing is there," according to the Associated Press, and the rocker stepped in to sing the part for her.

During the show, Bono, who co-founded the (RED) organisation in 2006 to raise awareness of the global AIDS battle, told the audience, "This is a celebration. This is an instigation. This is a provocation. This is not a charity concert."

He also performed a number of U2 tracks with The Edge, treating the crowd to renditions of classics including Stuck in a Moment You Can't Get Out Of and Angels of Harlem, and they teamed up with Irish singer Hozier to perform When Love Comes to Town.

Hozier also performed his hit Take Me to Church, and Jessie J covered Prince's Purple Rain.

Other highlights of the night included a spoken-word performance by The Walking Dead actress Danai Gurira, and speeches by veteran rocker Sting and former President Bill Clinton.
