Ozzy Osbourne’s kids are sharing subtle tributes to their late father. 

After the Black Sabbath frontman died July 22 at the age of 76, his and ex-wife Thelma Riley’s notoriously private kids Jessica Obsourne and Louis Obsourne celebrated his life on social media.

Jessica reshared a tribute by ON with Mario Lopez to her personal Instagram account. Alongside the post, the 53-year-old added her father’s song “Crazy Train,” and wrote in the caption, “RIP Ozzy.”

Meanwhile, her brother Louis, 50, took an even more understated approach to remembering his father by changing his profile photos online to all-black screens. 

In addition to the siblings’ individual nods to their father, Ozzy’s family—which also included wife Sharon Osbourne and their kids Aimée Osbourne, 42, Kelly Osbourne, 40 and Jack Osbourne, 39—shared a joint statement following his unexpected death. 

“It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning,” the family said in a statement to E! News. “He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time.”
