Kelly Osbourne paid tribute to her late father, Ozzy Osbourne, ahead of her first birthday without him. Osbourne, who turned 41 on Monday, October 27, shared a carousel of photos of herself and her dad via Instagram hours before the official start of her birthday. "Tomorrow is going to be a first for me. The first birthday without my dad," she wrote on Sunday, October 26. "Every year the thing I look [forward] to the most was spending the day with him and the cards he would write me. Knowing that I will never get one again shatters my heart. Here are just a few of them. They were always short, simple but said everything I needed to hear. I love you Daddy tomorrow will suck without you. 💔." Kelly's post included snaps of a few greeting cards her dad gave her over the years. One read, "To Kelly I love you with all my heart," while another said, "Dearest Kelly I just want to say that I love and miss you every second of the day." They were all signed, "Love Daddy." Kelly Osbourne's Quotes About Ozzy Osbourne's Illness Before His Death Ozzy died on July 22 at age 76 following a yearslong battle with Parkinson's disease and several major health scares. His cause of death was later revealed as a heart attack. Kelly spoke out about her father's death for the first time on July 24, quoting lyrics from "Changes," a Black Sabbath song released in 1972. "I feel unhappy I am so sad," she wrote via her Instagram Story at the time. "I lost the best friend I ever had 💔." She later shared a longer message about his passing, thanking fans for their support. "I've sat down to write this a hundred times and still don't know if the words will ever feel like enough.. but from the bottom of my heart, thank you," she wrote via Instagram in August. "The love, support and beautiful messages I've received from so many of you have truly helped carry me through the hardest moment of my life. Every kind word, every shared memory, every bit of compassion has meant more than I can ever explain." Kelly Osbourne Shares Sweet Throwback Clip With Dad Ozzy After His Death She continued, "Grief is a strange thing - it sneaks up on you in waves. I will not be ok for a while - but knowing my family are not alone in our pain makes a difference. I'm holding on tight to the love, the light and the legacy left behind." At Ozzy's funeral on July 30, Kelly paid tribute to her dad by wearing a pair of round wire-framed sunglasses similar to the ones that were his signature over the years. Ozzy shared Kelly, daughter Aimee, 42, and son Jack, 39, with wife Sharon Osbourne, whom he wed in 1982. He was also the father of daughter Jessica and sons Louis and Elliot, whom he shared with first wife Thelma Riley. The Osbourne family faced further loss earlier this month when Sharon's dog Elvis died. "I can't believe I am posting this but my darling Elvis passed away this week," Sharon, 73, wrote via Instagram on October 19. "He gave me 14 precious year[s]. He was by my side until the end. Rest in peace my darling boy! 💔."
