Piers Morgan, who publicly slammed Ariana Grande after she jetted out to Florida immediately after the Manchester Arena attack on May 22, on Sunday apologised to the pop artiste and admitted that he misjudged her.

Grande returned to Manchester on Sunday with a tribute concert for the victims of the May 22 bombing, and this promoted Morgan to call her an admirable young woman.

Taking to Twitter, he wrote: "I misjudged you, @ArianaGrande & I apologise. You're an admirable young woman & this is a magnificent night. Respect. #OneLoveManchester."

"2 weeks after ISIS bomb a pop concert, a bigger & better one's held in same city. What better way to say F**K YOU? #OneLoveManchester tv."

"I'll say this too about @ArianaGrande - she has a cracking voice. By far the best vocal performance tonight...#OneLoveManchester tv."

Morgan received a lot of backlash for criticising Grande for not visiting the victims who were injured in the bombing at her concert. The Queen was seen visiting victims at the Royal Manchester Children's Hospital, and pop singer Katy Perry immediately took to Twitter to comment, "God bless The Queen and her kind heart."

But Morgan was quick to reply: "Agreed. Might have been nice if @ArianaGrande had stayed to do the same."

The British television personality added, "If the Queen can visit the victims in hospital, so can the star they paid to see."

He also said he would have visited the injured if he were in Grande's place. "I can 100 per cent guarantee you I would stay and visit those who had been killed or wounded watching me perform."
