Kelly Osbourne reflected on the lost relationship with her estranged older sister, Aimee Osbourne.

The youngest daughter of late rock legend Ozzy Osbourne admitted on an episode of the “We Need To Talk” podcast that she’s not close with her sister, but that she did “respect her enough to, you know, keep her anonymity.”

“I believe there’s a reason for everything; it just wasn’t meant to be for her,” she explained of Aimee’s decision against participating in the family’s wildly successful reality show, “The Osbournes.”

“It was always me and Jack,” she said. “If I’m honest, my older sister didn’t really ever acknowledge me and my brother. She was just in her own world doing her own thing.

“And I do, to a certain extent, if I’m honest, feel as though she was embarrassed of us… the whole family.”

The Osbournes became a household name in the early 2000s when MTV shone a light into their lives as celebrities — and the children of rock royalty — with an unscripted show about the family.

The Prince of Darkness earned legions of new fans from the show, which also featured wife Sharon, and two of their three kids: Jack and Kelly. Aimee, who lived in the guest house at the time, opted out of appearing on the program.

The series premiered in 2002 and ran for four seasons, with a final curtain call in 2005.

“I’ll never really truly understand, it just felt that way,” Kelly noted. “We’re very different. Everything I am, she’s not. Everything she is, I’m not.”

She added, “Like, you couldn’t be more polar opposite. We’re like oil and water.”

“We’re very different. Everything I am, she’s not. Everything she is, I’m not.”

While reflecting on sibling dynamics, Kelly admitted that she resented not having a chance to learn from her older sister.

“I will tell you it’s one of the hardest things in my life that I never got a big sister, and I had to learn how to do certain things that a big sister should have taught you, on my own,” she said. “I do have a resentment there, I’ll have that forever.”

Kelly said there was no hope for a reconciliation.

“I respect her, I accept her, but… we’re different and that’s OK,” she said. “If you’re not going to accept me for who I am and constantly trying to change me and say horrible things about me and truly seem to thrive when I’m not doing well, I don’t want you in my life.”

Kelly and Aimee’s representatives did not immediately respond to Fox News Digital’s request for comment.

Aimee previously disclosed her reasoning for not appearing on the reality show while chatting on New York’s Q1043 radio station.

“For me, I had grown up around having a pretty well-known dad anyway, and… I always really valued my privacy within that family,” she said in 2020 per People.

“And for me personally, and for who I am, you know, as far as morally and also just to give myself a chance to actually develop into a human being as opposed to just being remembered for being a teenager, it didn’t really line up with what I saw my future as.”

She added, “It definitely worked great for the rest of my family, but for me, and who I am, I just knew it was never something that I would have been able to consider realistically.”
