Ariana Grande has suspended her European tour and cancelled her upcoming London shows following the terror attack at her Manchester show on Monday night (local time).
The pop star is also reportedly trying to contact families of the victims wanting to pay for funeral costs of those deceased.
A Twitter account devoted to the 'Problem' singer tweeted: "Ariana has reached out to the families who's loves ones died last night....she is gonna pay for the funerals". The message has been retweeted nearly 50,000 times.
Grande was scheduled to play shows at London's O2 Arena on Thursday and Friday. Those shows have been cancelled, along with all other shows until June 5, when she is set to perform in Switzerland.
Her New Zealand show will go ahead as planned.
"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," Grande's management said in a statement released to media.
"The London O2 shows this week have been cancelled as well as all shows through June 5 in Switzerland.
"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 violence. Our way of life has once again been threatened but we will overcome this together. Thank you."
A spokesperson from Live Nation entertainment told Newshub at this stage the Australian and New Zealand concerts will be going ahead as normal, with Grande bringing her Dangerous Woman tour to New Zealand for a show at Spark Arena on September 2.
Grande had finished performing in the Manchester Arena when a suicide bomber detonated an explosive device. Twenty-two people were killed, including children.
Shortly after the attack, Grande tweeted that she was "broken".
"broken. from the bottom of my heart, i am so so sorry. i don't have words," she said.
Grande returned to her home in Florida, United States, on Tuesday.
Other musicians have cancelled upcoming concerts in the United Kingdom out of respect for the victims. Cancelled acts include Blondie and Take That.
The UK terror threat level has been raised to critical.
