Kelly Osbourne Reportedly Splits from Fiancé Sid Wilson Just Seven Months After He Proposed

She was standing backstage at what would become her father's final concert when the man beside her got down on one knee. Months later — after Ozzy Osbourne's death and a period of personal upheaval — Kelly Osbourne's engagement is now over.

Kelly Osbourne and Slipknot DJ Sid Wilson, 49, have quietly called off their engagement, parting ways as Kelly, 41, navigates the aftermath of her father Ozzy Osbourne's death and a period of personal upheaval.

The couple shares a three-year-old son, Sidney, who is named after his father.

A source close to Kelly told the Daily Mail she has endured a difficult month, navigating the end of the relationship while keeping her focus on her son.

"Kelly and Sid have decided to call off their engagement. Kelly has been struggling following the loss of her father. The grieving process has been incredibly difficult, and she's been doing everything she can to cope."

According to the publication, the pressures between the pair had been present well before the separation became final.

"In truth, she and Sid have been facing challenges in their relationship for some time, and things were not as they appeared. They tried to make it work, particularly for the sake of their child, but ultimately decided that separating is the best path forward."

Speaking to People magazine, a source echoed the sentiment, revealing that the breakdown had been building for some time. "She's been in a challenging headspace for several reasons. It's been very emotional for her. She's had a lot going on," the source said.

"Ozzy's death still affects her deeply. She's very focused on being there for her mom right now. They're incredibly close and that's been her priority."

Differing priorities, the source added, had quietly chipped away at the foundation of the relationship.

"It's been hard for Kelly and Sid to balance everything, especially with different priorities about where to spend time. This has put a strain on their relationship."

The news sent shockwaves through social media, with fans rushing to share their heartbreak and support.

"Don't break up with Sid Kelly, that man is one of the best things that happened to you," one urged. "My heart is breaking 💔😢," another lamented. "I had a bad feeling about that. 😞 There's a lot of healing ahead," a third reflected.

The sympathy poured in alongside the disbelief. "Oh [expletive], what a horrible year this woman is having, sending prayers for her family, especially the young child they share," one fan sympathised.

"This is all horrible. He made it a point to propose in front of her sick dad too before he passed. They have a younger son too. Ugh that's so much to go through in a few months 😭," another grieved.

One fan claimed to have spotted the signs weeks earlier, writing, "She hasn't been wearing the ring for a month or so 😢."

Others turned to speculation. "Have a feeling they only got engaged for Ozzy," one suggested, while another apleaded, "Come on @kellyosbourne noooooo, think about it. I know that is hard, your Dad lost, but imagine that you left this world and who is going to take care of your beautiful baby???? Please go to therapy but don't quit."

Amid the noise, Kelly appeared to be pressing forward.

The day before the news broke, she had been captured on celebrity makeup artist Jourdan Walker's Instagram page, looking every inch the glamour queen, sporting a striking purple smokey eye, paired with a glossy nude lip — giving little away about the turmoil behind the scenes.

Then, on Monday evening, she turned her attention firmly to where it mattered most: her son. Kelly shared a playful selfie on her Instagram Stories alongside Sidney and a friend, all three wearing nappies on their heads, with Kelly's mouth wide open in a joyful grin.

"Little man has conjunctivitis so we are entertaining him 🤍 Thank the lord he is feeling better!" she wrote.

Kelly and Sid had known each other for more than two decades, first meeting during Ozzfest, before turning their long friendship into a relationship in 2022. On Valentine's Day that year, Kelly shared a photo of the pair and wrote:

"After 23 years of friendship, I can't believe where we have ended up. You are my best friend, my soulmate, and I am so deeply in love with you, Sidney George Wilson."

They welcomed their son later that year, soon after Kelly announced the pregnancy news with a photo of herself holding a sonogram, captioned:

"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. To say that I am happy does not quite cut it. I am ecstatic! 🤰

Sid proposed backstage at Black Sabbath's reunion concert in Birmingham on 5 July 2025, in front of the whole family, including Ozzy, Sharon, and her brother Jack. The post was simply captioned, "Oh and this happened yesterday!"

Kelly later said she had no idea the moment was coming.

Just weeks later, Ozzy died on 25 July at the age of 76, marking a significant period of change in Kelly's personal life.

Earlier this month, the media personality appeared to hint at the strain in a candid Instagram post, writing:

"I am going through one of the hardest periods of my life. I shouldn't have to defend myself, but I also won't allow myself to be dehumanised like this."

The day after the split was reported, she returned to her Instagram Stories sharing a passage that read:

"I am in love with this sentence: 'Forgive yourself for not knowing earlier what only time could teach.'"

Sources confirmed Kelly remains sober and is now focused on herself and her role as a mother. She was last pictured with Sid at the Grammy Awards in February.

Since then, she has kept a low profile, appearing only with close friends and her mother, Sharon, as she focuses on rebuilding her life and raising her son.
