Hozier has announced a series of livestream concerts for ISPCC Childline on social media.
"Myself and a few fantastic artists will be doing a series of streams for @ISPCCChildline," Hozier announced.
The livestream concerts will run for seven nights from 7pm beginning this Friday.
Hozier said it was a particularly difficult time for children in unsafe situations who were turning to Childline for support.
"It's for the children's smiles," he later tweeted, in response to people welcoming his support for the charity.
As the lock down is a particularly difficult time for children in unsafe situations, myself and a few fantastic artists will be doing a series of streams for @ISPCCChildline. Their calls have tripled in the last week. 7 nights from 7pm! I’ll see you this Friday. More info to come— Hozier (@Hozier) March 24, 2020
A spokesperson for the ISPCC Childline said the support from Hozier would make a huge difference for children at this critical time.
"Thank you so much, Hozier, and everyone giving of their time to make sure children always have somewhere to turn," she said.
ISPCC Childline says it will continue to be available on a 24/7 basis to every child and young person.
Contacts to Childline have continued to increase since schools closed due to Covid-19.
Online contacts were up almost 15% last week and website users increased by almost 4% over the same period.
Because of measures to deal with Coronavirus vital fundraising activities have had to be curtailed. ISPCC Childline has appealed for public support to ensure it can cope with the increased demand.
"It is a real pinch moment for us now, especially with more measures just announced," the spokesperson said.
Schools are set to remain closed until well beyond the end of the month to support efforts to combat coronavirus.
"We are seeing an increase in Childline contacts because children are at home and it may not be the ideal place for them to be," she said.
"We are set up to operate our online chat system remotely and we will continue to be there for the children.
"There are children who would turn to Childline in the middle of the night and the online system allows them to do that discreetly.
"So we will continue to be here at childline.ie regardless of what happens over the next few weeks."
Childline receives an average of 1,000 contacts every day from children and young people who know they can talk about anything on their mind.
Any child or young person in Ireland can contact Childline by chatting online at childline.ie or texting to 50101.
Information and support content is also available at childline.ie.
