Two of Ozzy Osbourne’s lesser-known kids, Jessica and Louis Osbourne, quietly honored the late rocker after being left out of the family tribute.

After news that the Black Sabbath vocalist passed away surfaced, both Jessica and Louis, whom Ozzy shared with his first wife, Thelma Riley, took to social media to subtly pay their respects.

Louis, 50, simply changed his Facebook profile picture to a black square.

Jessica, on her end, took to her Instagram Stories to repost a tribute from the “On With Mario Lopez” podcast. She wrote, “RIP Ozzy,” above.

On Tuesday, Ozzy’s family confirmed he had died earlier that day. He was 76. 

“It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning,” the statement read.

“He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time,” they added before signing off as Sharon, Aimee, Kelly, Jack and Louis.

The family did not share any further details about the Prince of Darkness’s death.

Jessica and Elliot — whom Riley gave birth to during a previous relationship and Ozzy had adopted during their marriage — were notably left off the statement.

Although not much is known about Elliot and his relationship with Ozzy, the singer was estranged from Jessica, whom he and Riley welcomed first in 1972.

“My recollection from my childhood with dad is that he’d be away for very long periods of time, and there’d always be a period of adjustment when he came home, and then it’d get to normality and then he’d go again,” she said in the 2011 release of “God Bless Ozzy Osbourne,” per E! News.

“So, it was a very erratic childhood with dad.”

In the years leading up to Ozzy’s death, he was suffering from several debilitating health ailments, including Parkinson’s disease and a spinal injury.

Earlier this month, the rockstar performed his final show with his Black Sabbath bandmates at the Villa Park Stadium in Birmingham, England.

Ozzy’s final Instagram post was also a tribute to his last show with his bandmates: Tony Iommi, Bill Ward and Geezer Butler.

After Ozzy’s death, the remaining members of Black Sabbath paid tribute to their “brother” on social media.

“My dear dear friend Ozzy has passed away only weeks after our show at Villa Park,” Iommi wrote.

“I can’t really find the words, there won’t ever be another like him,” the guitarist added. “Geezer, Bill and myself have lost our brother.”
