Devon soul singer Joss Stone is helping to raise funds for a life-saving brain tumour treatment for a seven-year-old boy.
Jasmine and Rad Novakovic are making a desperate public appeal to send son Alex to America for specialist radiotherapy treatment.
He was misdiagnosed as having a migraine.
Joss, whose lives near Ashill, alerted her fans on Facebook and since then donations have poured in with over £40,000 raised in just three days.
Thanking them, Joss said: "We have so much power when we unite for good."
