Sharon took to Instagram on Tuesday to commemorate the milestone with a sweet black-and-white snapshot from the couple's early days.
"Thank you Ozzy for 35 crazy & wonderful years," the 65-year-old TV personality captioned the sweet throwback. "Here’s to the next chapter of our lives. Love you more today than yesterday. Always remember: You carry my heart in yours, and it’s getting older and needs protecting. Happy Anniversary."
"Happy Anniversary My Love, You Are My Everything!" the former Black Sabbath frontman wrote in the caption.
The couple's daughter, Kelly Osbourne, jumped on board the crazy train of adorable throwback pics with another sweet snapshot from their wedding ceremony, which showed off more of her mom's lace-covered wedding dress and her dad's white tux.
"Happy 35th anniversary mum and dad thank you for showing me what true love really is!" Kelly wrote.
