Jack Osbourne and his mother, Sharon Osbourne, recently reunited with his older sister, Aimee Osbourne, reportedly coming as an unwelcome surprise to the third Osbourne sibling, Kelly.

A source told the Sun that the family powwow has “proven painful” for Kelly.

“Kelly is currently not on speaking terms with Aimee, and she was shocked to see the cozy reunion between the three of them,” the insider noted.

A spokesperson for Kelly did not reply for comment.

Last month the “DWTS” alum, 42, revealed she has permanently cut ties with Aimee, 43.

“If I’m honest, my older sister didn’t really ever acknowledge me and my brother,” the “Osbournes” alum said on the “We Need To Talk” podcast.

“She was just in her own world doing her own thing. I do, to a certain extent, feel as though she was embarrassed of us,” Kelly added.

“We’re very different,” the reality star explained. “Everything I am, she’s not. Everything she is, I’m not. Like you couldn’t be more polar opposite. We’re like oil and water.”

Kelly firmly declared there would be no reconciliation between the sisters.

“I respect her, I accept her, but we’re different, and that’s OK,” she explained. “If you’re not going to accept me for who I am and constantly be 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.”

In 2025, Jack, 40, revealed in an interview that he also did not have a good relationship with Aimee.

“We’re not close at all,” he divulged. “We don’t have a great relationship — she’ll be the first to tell you that, so it’s no secret.”

The three siblings did make a rare appearance at the 2026 Grammys to honor their father, Ozzy Osbourne.

The Black Sabbath frontman died in July 2025, aged 76, from a heart attack as well as coronary artery disease and Parkinson’s disease.
