Kelly Osbourne is reminiscing on her close bond with dad Ozzy Osbourne after his death. In an Instagram Story uploaded Monday, July 28, Kelly, 40, shared a throwback interview clip where she joked, "I know I can't say f***. I have to behave myself." Kelly was sitting on Ozzy's lap in the video. "You can't say what?" he replied. "Terrible, isn't it, the way children speak these days?" Kelly then told her dad that she "learned from" him. "You learned from the best," he noted as they shared a hug. Kelly Osbourne's Quotes About Ozzy Osbourne's Illness Before His Death The social media post came less than a week after Ozzy's loved ones confirmed his death at age 76. "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," read a statement from his family on Tuesday, July 22. "He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time. Sharon, Jack, Kelly, Aimee and Louis." Kelly got candid about her father's passing in a follow-up message shared via her Instagram Story. "I feel unhappy, I am so sad," she wrote on Thursday, July 24. "I lost the best friend I ever had." Weeks before his death, Ozzy played his final concert with Black Sabbath, marking the band's first performance together in 20 years. Ozzy took the stage amid his battle with Parkinson's disease, which he first addressed in 2020. "You wake up the next morning and find that something else has gone wrong. You begin to think this is never going to end," Ozzy told The Guardian in a May interview about how the illness affected his ability to walk. Ozzy Osbourne and Wife Sharon's Family Album With Aimee, Kelly and Jack Ozzy went on to describe his preparation for his final performance, adding, "I do weights [and] bike riding, I've got a guy living at my house who's working with me. It's tough. I've been laid up for such a long time. I've been lying on my back doing nothing and the first thing to go is your strength. It's like starting all over again." Kelly, for her part, defended her father before his death while shutting down rumors about his health. She clapped back at one social media troll who claimed she didn't "understand how Parkinson's disease works." "This is the s*** I wake up to," Kelly wrote via Instagram alongside a screenshot of the message. "Wtf is wrong with people?" She continued: "Believe me I fully understand how this works. Your message is incredibly rude. So firstly I want to tell you to go f*** yourself! He is not in stage 5!! That is not the way his kind of Parkinson's works."
