Happy birthday, Ozzy Osbourne!
The legendary Black Sabbath rocker turns 65 today and he's ringing in the milestone B-day by asking fans to donate to charity instead of giving gifts.
The Royal Marsden Cancer Charity is a U.K.-based organization that provides treatment and care for more than 50,000 cancer patients every year in addition to funding cancer research.
Meanwhile, Ozzy's famous family members are giving the musician a some special birthday shout-outs via social media.

Happy birthday Dad I am so proud to be your daughter! I love you sooooo much!!!!!" she captioned the Instagram pic.
