Kelly Osbourne and Sid Wilson's Relationship Timeline

Kelly Osbourne met Sid Wilson two decades before they started dating — and it was all thanks to dad Ozzy Osbourne. Kelly met Wilson in 1999 when his band Slipknot toured with Ozzfest — the music festival founded by her parents. The pair developed a lasting friendship before officially confirming in February 2022 that their relationship had turned romantic. “After 23 years of friendship I can't believe where we have ended up!" Kelly wrote in a February 2022 Instagram post. “You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson." In May 2022, Kelly announced that she and Wilson were expecting their first baby. “I know that I have been very quiet these past few months so I thought I would share with you all as to why… I am over the moon to announce that I am going to be a Mumma,” she wrote via Instagram at the time. “To say that I am happy does not quite cut it. I am ecstatic!” The couple welcomed their son, Sidney Wilson Jr., in November 2022. More than two years later, Wilson proposed backstage at a July 2025 Black Sabbath concert.

Kelly and Wilson first met on the Ozzfest tour, a music festival founded by Kelly's parents, Ozzy and Sharon Osbourne.

Kelly shared a handful of photos via Instagram Story in celebration of Wilson's birthday. 

Kelly documented her trip to Ireland with friend Kip Zachary, taking to Instagram to show off a picture of herself posing with a large screen-printed pillow of Wilson’s face.

“Everywhere I go I take my baby with me,” she captioned the slide at the time.

Following her European adventure, Kelly once again hinted to her social media followers about her love for the rocker, posting a quote via Instagram Story and tagging Wilson.

“&& so there's this boy, And the way he laughs makes me smile, And the way he talks gives me butterflies, And everything about him, makes me happy," the quote read.

The couple was photographed attending a gathering for Kelly's niece Minnie in Los Angeles.

"Happy birthday Min Min I can't believe you are 4!!! 🎂🎁🎈," Kelly captioned an Instagram photo of the event.

The songwriter also posted an Instagram Story of herself and Wilson with her parent’s dog Wesley at the time. 

"Wesley is not just dad's favorite but he is Sid's favorite too!" she wrote.

The lovebirds exchanged sweet social media declarations to each other on Valentine's Day, confirming their romance. 

"After 23 years of friendship, I can't believe where we have ended up!" Kelly captioned a photo of her and Wilson sharing a kiss. "You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson. 💜"

Wilson, for his part, shared the same picture of the couple on his Instagram feed.

"There are not enough colors to display the palette of Love I have for you in my Heart 💜 Happy Valentines Day my Love XoXo,” he wrote under the post.

Kelly's brother announced on his Instagram that he and his then-finacée Aree Gearhart were expecting their first child. (Jack already shares Pearl, Andy, and Minnie, with ex-wife Lisa Stelly.)

“Exciting news,” the reality star captioned a post of the interior designer’s baby bump. “@seecreature and I are expecting a baby in the summer! Baby No. 4 here we come!”

Kelly, for her part, hinted at her own possibly pregnancy with Wilson at the time, writing, “There is no one more excited for this baby and you know why!!!!!!!!”

Kelly announced that she is expecting her first child with an Instagram slideshow of herself posing with various sonograms of her future little one.

"I know that I have been very quiet these past few months so I thought I would share with you all as to why…” she wrote. “I am over the moon to announce that I am going to be a Mumma. To say that I am happy does not quite cut it. I am ecstatic! 🤰💜."

The DJ posted the same sonogram pictures to his own social media, captioning the photos with only a variety of hearts and family emojis. 

Kelly’s mother, Sharon Osbourne, announced that her daughter and Wilson had secretly welcomed their son in November 2022. “They’re doing just so great. So great. She won’t let a picture go out of him,” she revealed during an episode of the U.K.’s The Talk. “I’m so proud of her.”

Kelly later expressed her displeasure with her mother’s reveal. “I am not ready to share him with the world,” she wrote via her Instagram Story. “It is no one’s place but mine to share any information on my baby.”

Kelly and Wilson walked the Grammy Awards red carpet in matching black looks. In addition to sporting a gas mask, Wilson complemented his partner’s purple hair by wearing a patterned scarf featuring purple fringe.

Kelly praised her partner in a sweet Father's Day tribute, writing via Instagram, "Any one can be a dad but very few are actually father’s. @sidthe3rd you are one amazing father I am honored and beyond lucky to be on this journey with you. Thank you giving me the greatest gift life has to offer. 💜."

In an exclusive Us Weekly cover story, Kelly hinted at her next steps with Wilson. "I definitely want more babies!" she told Us. "I found my guy. We don't need the certificate. But I know Sid really wants to get married, so we will get married. It's not as important to me. I've worn so many beautiful dresses and had so many moments that have been just about me, so that whole idea of a big day isn't as important to me."

Wilson proposed while backstage at Ozzy's final Black Sabbath concert. "Oh and this happened yesterday!" Kelly captioned an Instagram video of the romantic moment.
