Bungling Black Eyed Pea Will.i.am appeared to forget what city he was in at tonight's concert in memory of the Manchester terror victims.

He mistakenly shouted 'what's up London' while taking to the stage for the gig at the Emirates Old Trafford cricket ground while wearing a dazzling white suit and his trademark hat.

It came just seconds after Ariana Grande gave him a hint about the location of the concert by yelling: 'Manchester, make some noise for the Black Eyed Peas.'

The American rapper's geographical blunder left the crowd baffled - with Twitter users criticising the 42-year-old for having 'the nerve' to get the name of the city wrong.

One Twitter user joked that Will.i.am had become 'Where.Am.I'

Online commenters criticised the American rapper for having 'the nerve' to get the name of the city wrong

The geographical blunder left the crowd baffled and viewers at home equally confused

Twitter user Jamal Woon said: 'So we gonna ignore the fact Will.i.am just said "what's up London"'

He was also slammed for urging the crowd to 'put one finger in the air' - a gesture similar to the salute used by ISIS.

The Islamic symbol has been hijacked by the terror group who are often pictured making it before jihadi missions.

It gesture alludes to the religion's belief of tawhid that there is one God and that he was unique in creating the universe.

Will.i.am said on stage: 'We are here and we are together and we are one. Put one finger in the air. If you're about oneness, togetherness, put one finger in the air.'

The one-finger salute makes up the first half of the shahada – an affirmation of faith recited during daily prayers which experts say has been hijacked by ISIS fighters.

Rita Katz of SITE intelligence group said: 'The gesture has been used by jihadis for years, including high profile ones like Osama bin Laden.

'Within the jihadi context, the raised index finger takes on political meaning as well, widely rejecting any form of government not under Shariah law.'

After his turn on the stage, Will.i.am took to Twitter to defend himself over the London bungle.

He wrote to his millions of followers: 'There was an attack in London last night...I was paying homage and showing love to London and Manchester...'

Hundreds of audience members made the one-fingered gesture in unison leading to criticism on Twitter

One Twitter user wrote: 'Will.i.am has had a shocker. Repeatedly says he's in London despite being in Manchester and then gets the crowd to do an ISIS salute'

Another asked: 'Wtf why were they all doing the ISIS one finger salute?'

One user added 'Will.i.am gets #OneLoveManchester to do the ISIS salute FFS' and added an eye-rolling emoji

But Twitter users were not impressed, with one writing: 'This is literally a benefit concert for Manchester and Will.i.am has the nerve to say "what's up London".'

Another added: 'Will.i.am has had a shocker. Repeatedly says he's in London despite being in Manchester and then gets the crowd to do an ISIS salute.'

Some 60,000 brave and defiant fans joined Ariana Grande at her One Love concert at the Old Trafford Cricket Ground to stand together in the face of terrorism and pay tribute to those killed in extremist attacks.

Justin Bieber, Katy Perry, Coldplay, Pharrell Williams, Usher, Robbie Williams, Little Mix and One Direction star Niall Horan are also performing for free to raise at least £2m toward the We Love Manchester Emergency Fund.

But despite the atrocities, fans - including those injured in the Manchester Arena on May 22 - have been pictured in their droves at venue, proudly wearing clothes emblazoned with the slogan, 'We stand together'.

The American singer's manager Scooter Braun said the Manchester gig now had a 'greater purpose' than ever after the country's second terror attack in two weeks.

Mumford and Sons frontman Marcus Mumford sang 'you are not alone in this' as he performed an acoustic version of the band's hit Timshel to open the One Love Manchester benefit concert.

The event saw the US popstar return to the stage for the first time since suicide bomber Salman Abedi detonated a device, killing 22 of her fans and parents as they left her show at the Manchester Arena

In between renditions of Giants and Rule The World, Gary Barlow told the crowd: 'Thank you everybody for coming out tonight, thank you for everybody watching at home, thanks to Ariana for inviting us tonight.

'Our thoughts are with everyone that's been affected by this. We want to stand strong, look at the sky and sing loud and proud.'

Barlow then introduced his former band mate, Robbie Williams. Williams serenaded the crowd with his song, 'Strong', changing the words to, 'Manchester we're strong'.

U2 frontman Bono sent a video message to the concert, telling the crowds: 'All our hearts are with you, all our hearts are with Manchester and with the UK. So many of our friends are in this great city.

In another poignant moment, Robbie Williams joined his former Take That band members on stage

'We're broken-hearted for parents who've lost their children and children who've lost their parents in this senseless, senseless horror. There is no end to grief and that's how we know there is no end to life.'

Pharrell Williams then opened his performance with a rendition of Get Lucky, his hit with Daft Punk, before Miley Cyrus joined him on stage to perform Williams' hit Happy.

Before welcoming Cyrus to perform, Williams said: 'You know why I'm bowing, I'm bowing because despite all the things that have been going on in this place, I don't feel or hear or see any fear in this building. All we feel here tonight is love, resilience and positivity. '
