Singer Sinead O'connor has cancelled all her planned concerts for 2015 after one of her sons was diagnosed with a life-threatening illness.
The "Nothing Compares 2 U" hitmaker, who has three sons and a daughter, took to Facebook to post an emotional message.
"Please accept my sincerest apologies. My child has been suffering with a life-threatening medical condition since early March 2015. It is the type of condition my child will definitely survive, if correct care is taken and is supervised by myself. Otherwise there is no guarantee. That is the plain truth," she wrote.
"Needless to say, this has been and remains a severe family crisis. Like any mother, I have been up all day and night every day and night since I found out my child is suffering...
"I have been instructed by my child's doctor not to work until my child has fully recovered... I have also been separately instructed by my own doctor, not to work... It doesn't please me or suit me at all to let people down. I'm told it will be impossible for me to be employed as a live performer for three years now because I have cancelled the tour. So be it.
