Ariana Grande Manchester Benefit Concert Line-Up Adds Little Mix And Robbie Williams

It's going to be an all-star event.

Three acts have been added to the line-up of Ariana Grande’s One Love Manchester benefit concert, including two British ones.

Little Mix and Robbie Williams will both be taking to the stage at Manchester’s Emirates Old Trafford cricket ground on Sunday (4 June), as well as the Black Eyed Peas, whose involvement had been teased earlier in the week.

Organisers have confirmed that the line-up is now complete, with Miley Cyrus, Katy Perry, Justin Bieber, Take That, Coldplay, Niall Horan, Usher and Pharrell Williams already having been announced as performers on the night.

Tickets for the benefit event went on sale on Thursday (1 June), selling out in just six minutes, with those in attendance at the Ariana Grande concert where the Manchester bombing took place receiving free tickets.

In a statement, event organisers said: “We understand that there are a number of fans who didn’t receive an email this morning with regards to free tickets for One Love Manchester. We worked through the night and verified thousands of original bookings although there were some we could not verify.

“We want to give all fans who were at the show, regardless of where they bought their tickets, every opportunity to register for One Love Manchester, so we have opened up the registration again today (1 June), until 2pm. “

Those who need to register for tickets can do so here, by providing their booking reference and information about where they bought their ticket, including the venue box office, or ticketing websites.

Music fans who weren’t able to bag tickets will still be able to watch along at home, with the BBC broadcasting the whole show live from 6.55pm on Sunday.
