As tributes continue to pour in, two of Ozzy Osbourne's children — Jessica and Louis — have honored their late father in subtle ways after the former Black Sabbath frontman and legendary rocker died on Tuesday,

Morrison — who played guitar in Idol’s band — noted that his “thoughts and [his] love” are with Ozzy’s wife, Sharon Osbourne, and their kids, Jack, Kelly and Aimee. (Ozzy was also the father of Elliot, Louis and Jessica, whom he shared with ex-wife Thelma Riley .)

At the end of her July 22 Mayhem Ball performance in San Francisco, Gaga exposed an Ozzy Osbourne T-shirt underneath a black leather jacket, then played his 1980 debut solo single “Crazy Train” as she and her dancers walked a catwalk.

After news of the Black Sabbath vocalist’s death surfaced, Jessica and Louis Osbourne took to social media to subtly pay their respects to their late dad.

Ozzy Osbourne's eldest children from his first marriage, who are not well-known, have reacted to his painful passing.
