The 61-year-old 'X Factor' judge decided to make the generous donation to a man named Ryan Glenny, 23, after learning that he was diagnosed with a terminal bowel cancer last month, reported Daily Mirror.
Glenny's friend Ashley Clark decided to make an online funding page to garner some monetary support for his friend.
Osbourne donated 10,000 pounds to Glenny and his family.
"Mrs Sharon Osbourne wanted to donate 10,000 pounds to Felix and family and this is the note she wanted: 'Dear Felix, From a survivor, never give up the fight and hope. God Bless you and your family. Love, Sharon Osbourne'," read a message posted to the fund-raising page by Clark.
