The website of the Irish Cancer Society crashed last night after Majella O'Donnell had her head shaved live on the Late Late Show for the charity.
"The flood of goodwill after Majella on the Late Late Show has crashed our text and website," the charity said last night.
"We're working to resolve it, please bear with us."
The businesswoman and wife of singer Daniel got a standing ovation on the show after she shaved her head for the charity live on the show.
"Am I better bald," she joked to host Ryan Tubridy after she looked at herself in the mirror after having her head shaved.
Majella added that she has just started chemotherapy.
She also revealed how she can't pray for herself because it makes her think too much.
"I can't pray for myself because I can't think about it that much. I can't sit down and say 'God help me' becuase I don't feel that I need help. I can't explain it and if it was a friend of mine diagnosed with cancer I'd be praying for them but I can't seem to do it for myself.
"I know that so many people are praying for me and that amount of power creates power.
"I'm only speaking for myself...I don't feel sick," she told Ryan Tubridy on the Late Late Show as she explained that feeling good might not last.
Earlier she had said she would be too afraid to look but then defied her fears.
"I'm only here to raise awareness and funds for the Irish Cancer Society and I don't need attention in this arena for this kind of thing."
She explained that she had discussed how to raise cancer awareness with her husband.
“Having spoken to Daniel, we agreed that we would like to use this as an opportunity to raise awareness and funds. We were both delighted when The Late Late Show and Ryan agreed to facilitate our request.”
She added that the aim is to raise as much money as possible. “I would love it if anyone who would like to contribute to this most worthwhile cause, could start donating today”
People can donate to Majella’s Pink Appeal for the Irish Cancer Society, text ‘Pink’ to 50300 to donate €4 or CallSave 1850 60 60 60 to make a donation.”
John McCormack, chief executive of the Irish Cancer Society said: “Majella is extremely brave to take the huge step of shaving her hair on national television.”
He added: “Losing your hair to cancer treatment can be a devastating time for many women, as can proactively shaving your hair.
“The Irish Cancer Society fully support Majella and I personally commend her for bringing light onto such a painful time in her life, in doing this Majella will help other people out there now with breast cancer know that they are not going through this alone.”
The Society is 95pc funded by the general public, receiving less than 5pc government funding.
