Ariana Grande’s stand up comic ex-fiancé was branded “disgusting” for joking about the Manchester terror attack.

Ariana has reportedly now split from Pete Davidson after a tough few months which also saw her rapper ex Mac Miller die from a suspected overdose.

She is taking time out to come to terms with his shock death, and it's said it 'simply wasn’t the right time' for her and Davidson.

Comic Davison made the gag this summer in a stand-up routine after 22 people were killed by a suicide bomber at an Ariana concert last year.

A mum whose daughter was murdered told the Sunday Mirror at the time: “This is heartbreaking and outrageous.”

Davidson, whose fireman dad died in the 2001 Twin Towers attack, included the joke in one of his trademark bad taste routines.

He said Ariana must have realised how famous she had become because “Britney Spears didn’t have a terrorist attack at her concert”.

Charlotte Hodgson, who lost her 15-year-old daughter Olivia Campbell-Hardy in the attack, said: “For anyone to joke about this situation is disgusting and I think he should publicly apologise for it.

“The families will find it equally as disgusting.

"We don’t need jokes about it, there have been plenty around, and it’s heartbreaking to hear every day.

“But for someone so famous to be doing it and now to be with Ariana, it’s outrageous. I think she would be horrified too.”

Jade Clough, 30, who survived the Manchester Arena attack, said she was “shocked” by Davidson’s joke.

Education project worker Jade suffered nerve damage after a bolt severed tendons in her foot and had therapy for her mental anguish.

The mum of one said: “I think it’s absolutely disgusting, I’m shocked.

“This isn’t something to joke about, it was a terrorist attack targeted at children. You don’t joke about things like that in a stand-up comedy show.

“I’m still suffering on a daily basis, I still have nightmares, and Ariana herself has suffered from PTSD. What the hell?”

Davidson, 24, and Ariana, 25, met in 2016 when she presented cult US TV show Saturday Night Live, which he appears on.

They both split from previous partners in May and announced their engagement in June.

Davidson made the joke at the Laugh Factory in Los Angeles five months after the May 22, 2017 blast.

Sources said it caused a stir even though he is famous for comedy roasts, in which stand-ups try to out do each other with crude barbs.

One onlooker said: “It drew gasps from the crowd and everyone squirmed in their seats, the event five months earlier was still pretty fresh, and there were plenty of British tourists in the crowd.”

She has revealed she suffered from post-traumatic stress disorder after the terror attack.

People with PTSD can suffer from flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the event that sparked their trauma.

Ariana has previously described feeling guilt for discussing her struggles after the blast.

She explained: “I know everyone there experienced a tremendous amount of it as well.

"I feel like I shouldn’t even be talking about my own experience – like I shouldn’t even say anything.”

Davidson declined to comment on the joke, but sources close to him who were at the show said: “His set received a standing ovation.”
