More details of Ariana Grande’s One Love Manchester concert have been revealed as the organisers confirm the event WILL go ahead following a terror attack in London.

MTV will livestream Ariana’s benefit concertwhich fans can watch via onelovemanchester.mtv.com on Sunday 4 June from 6.55pm BST.

The Sun on Sunday reveals Ariana is planning a duet with the Black Eyed Peas to sing a version of Where Is The Love as part of the concert – which will also see performances from Miley Cyrus, Justin Bieber, and Katy Perry, among others.

The One Love Manchester benefit has been organised after a suicide bomber killed 22 outside the singer’s Manchester Arena concert on May 22.

Ari’s manager, Scooter Braun, released a statement on Sunday following the news that a fresh terrorist attack had taken place in London on Saturday night to confirm that the One Love Manchester event would go ahead in defiance of terrorism.

“After the events last night in London, and those in Manchester just two weeks ago, we feel a sense of responsibility to honour those lost, injured, and affected,” Scooter said.

“We plan to honour them with courage, bravery, and defiance in the face of fear. Today's One Love Manchester benefit concert will not only continue, but will do so with greater purpose. We must not be afraid and in tribute to all those affected here and around the world, we will bring our voices together and sing loudly,” he continued.

“I am pleased to say we have the full support of Greater Manchester Police and the Government and are assured the safety of all those attending is the highest priority. All artists involved have been unwavering in their support this morning and are determined to carry on with the show. We ask the strong city of Manchester and the world to join us in making the statement that hatred and fear will never win.

“Today we stand together. Thank you,” he said.

'MTV stands strong with all of you in the fight against global terrorism. Recent attacks in Manchester UK, Kabul Afghanistan, Minya Egypt, Baghdad Iraq and London UK are remindersof the countless people who have lost their lives in terrorist acts, but the One Love benefitconcert is a reminder to us all that we're always stronger together.'
