Kelly Osbourne made a heartbreaking promise to her dad Ozzy before his death. As Perezcious readers know, the rock legend died last week after a years-long battle with Parkinson's disease. He was 76. His family just mourned his loss on Wednesday by taking part in a teary funeral procession in England. Ozzy was open about not wanting his funeral to be a "mope-fest"... and it sounds like his daughter is taking that to heart. While she's obviously unbearably sad about the loss, she's doing her best to stay strong for her family, including her mom Sharon, an insider told DailyMail.
