ARIANA Grande led the celebrity tributes following the London terror attack which killed seven and left at least 48 people injured.

The heinous attack – which happened in the London Bridge area of the capital on Saturday night – came less than 24 hours before Ariana’s One Love Concert, which was organised to raise money for those affected by the Manchester bombing.

On hearing the news, Ariana, who is currently in the UK preparing for the gig, told her followers: “Praying for London.”

And today, her manager Scooter Braun promised to 'honor those lost injured or affected' in both attacks at the concert.

He posted an Instagram statement which read: "After the events last night in London, and those in Manchester just two weeks ago, we feel a sense of responsibility to honor those lost, injured, and affected.

"We plan to honor 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."

A picture taken outside the Wheatsheaf pub in Borough Market shows the three terrorists lying dead – after being gunned down by cops.

Four explosions – confirmed by police as controlled blasts – were heard outside The Sun offices near London Bridge between 1:23am and 1:49am.
