Kelly Osbourne is still mourning the loss of her dad Ozzy Osbourne and opening up about the "resentment" she holds from his final days.

Kelly, along with brother Jack Osbourne and mother Sharon Osbourne, reflected on the life, legacy and heartbreaking loss of the Black Sabbath rocker on the Wednesday (November 12) episode of their family's podcast The Osbournes Podcast. After tearfully wishing she "wanted more time" with her late father, Kelly admitted she still has "one resentment" from one of her last interactions with the legendary musician, per People.

"I always heard Dad going down the stairs in the morning," she said. "And the first thing I always said to him was, 'Morning, Dada, I love you.' And I'd call it out, and he'd say, 'I love you more' and walk down the stairs... And on the morning that he passed, I didn't say it."

Sharon was quick to assure her daughter that Ozzy "knew so much" that Kelly loved him.

"One thing, Ozzy was great, and he was a master of acting — not dumb... checked out. He was a master of that," she said. "He knew everything that was going on."

The rocker's family announced on July 22 that he had passed away at the age of 76, weeks after taking the stage for the final time during the Back to Beginning concert in Birmingham, England. His cause of death was later revealed to be the result of a heart attack with "joint causes" of coronary artery disease and Parkinson's disease with autonomic dysfunction.
