An account dedicated to the pop superstar claims that the devastated singer has pledged to help the families of the 22 people who lost their lives in the bombing of Manchester Arena following her concert.
The site, called Ariana Updates!, shared a post saying: 'News on Ariana: Ariana has reached out to the families who's loves ones died last night....she is gonna pay for the funerals!'
A rep for the star has not confirmed the claims, but tells MailOnline: 'Due to the tragic events in Manchester the Dangerous Woman tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost.
'We ask at this time that we all continue to support the city of Manchester and all those families affected by this cowardice and senseless act of violence. Our way of life has once again been threatened but we will overcome this together.'
She has since suspended her Dangerous Woman tour and jetted home to the US.
The claims come after nine of the victims were named, including eight-year-old Saffie Roussos and 18-year-old Georgina Callander.
Ariana had previously met Georgina at a fan meet-and-greet, posing for a picture with the beaming teen.
As the chaos following the attack unfurled on Monday night, it has been claimed that the singer's mother Joan immediately escorted terrified fans to safety backstage after the explosion was first heard.
The site reports that Joan had still been sitting in her seat on the front row when the bomb detonated in the venue's lobby after the show - and was quick to come to the aid of surrounding fans.
Fellow concert-goers reveal Joan had called as many as 10 children to follow her backstage, leading them to safety seconds after the attack that has killed 22 and left 119 injured.
The site reports that Joan had been preparing to visit her daughter backstage and congratulate her on another tour performance, when the suicide bomber targeted the sell-out concert.
Eye-witnesses state Joan, flanked by Ariana's security team, had then escorted a large group of fans sat close the stage out of the concert hall and into to the dressing rooms.
The singer's mother reportedly comforted the panicked youngsters there until they were safely evacuated by police, who arrived on the scene soon after.
