Kelly Osbourne's final wish to her late father was reportedly not to "crumble in public" after his death

A source has now told the Daily Mail: "The last few days have been a tough ride, but Kelly has been focused on ex ecuting plans with her mum.

"Of course there have been tears, but she promised her dad - who openly spoke about not wanting people to mourn but rather celebrate his life - that she would not crumble in public."

Kelly was seen holding her mother Sharon close on Wednesday as she placed a rose on a growing mound of floral tributes at the Black Sabbath Bridge, a spontaneous memorial for Ozzy.

Ozzy had always encouraged his family to "celebrate what people have done in life" and "not f****** worry about what's next", the insider also told the Mail.

While Kelly has embraced that ethos, those close to the family are said to be deeply concerned for Sharon, who has faced health battles including colon cancer surgery and chemotherapy in 2002.

A source said: "She and Ozzy were such a unique couple and them being apart is heartbreaking."

Sharon and Ozzy's relationship was famously turbulent but enduring.

They met in 1970 when Sharon, then 18 and daughter of Ozzy's manager, began managing Ozzy's career after he left Black Sabbath.

The couple married on 4 July 1982 in Hawaii and celebrated 43 years of marriage this year, just before Ozzy's farewell concert, Back to the Beginning.

Kelly is also said to be drawing strength from her close bond with her brother Jack, 39, and her partner Sid Wilson, 48, to whom she got engaged at the end of Ozzy's final gig in Birmingham just over two weeks before his death following a Parkinson's battle and fights with the agony of back surgeries.

Kelly and Sid, a member of Slipknot, have a son, Sidney, born in November 2022.
