Liam Gallagher has dramatically stepped in to save the BRITs tribute to Manchester Arena bomb victims after Ariana Grande pulled out.

The former Oasis frontman will now perform an emotional dedication to the 22 who lost their lives in May last year in what has been described as the “biggest talking point of the night”.

Liam may sing Live Forever, which he sang with Chris Martin at the Manchester One Love concert.

A source said: “Liam has saved the day by stepping in at the last minute. It's a perfect choice. It's going to be the moment of the evening.”

Ariana was forced to pull out after being 'ordered by doctors not to fly' after falling ill at the last minute, an insider disclosed to the Mirror.

The Mirror told how Ariana Grande left organisers “frantic” after pulling out in the last 24 hours and how it was a “race against time” to find a replacement.

A source said: “It was utter chaos when the call came in that Ariana couldn’t do it.”

Bosses had planned the tear-jerking segment which sees the names of the 22 people who died last May screened during the performance.

Earlier this month, Liam accused organisers of refusing to let him play live.

He wrote on Twitter: “So the Brit awards have ballooned it again. All I wanted to do was play LIVE but there too scared.”

Ariana had been lined up as the surprise guest at the 2018 Brit Awards but pulled out with less than 24 hours to show time.

A source said: “It was utter chaos when the call came in that Ariana couldn't do it. It's race against time to get someone to do what is very much the centrepiece of the entire show.”

The Mirror exclusively told today how bosses had planned the tear-jerking segment which sees the names of the 22 people who died last May screened during the performance.

A source told us: "It will be the biggest talking point of the night. The whole industry wants to come together to pay their respects to the victims.

"The effects of that terrible night resonated far and wide in the music industry and it's only right everyone comes together to pay their respects."

After the tragedy, Ariana organised the One Love concert, with a line-up that included Take That and Coldplay.

This month 24-year-old Ariana's manager told how the singer cried for days and felt "every name" of the victims.

Scooter Braun, 36, said he and the singer had met 19 families who had lost loved ones, which had been the "hardest two hours of either of our lives".

He revealed how Ariana was so traumatised by the bombing she had questioned whether she could sing again.

At last year's Brits, Wham! legend Andrew Ridgeley paid an emotional tribute to George Michael, who had died on Christmas Day in 2016.

Coldplay's Chris Martin performed George's A Different Corner, accompanied by a string orchestra.
