Kelly Osbourne's cryptic message after Slipknot reportedly fired her ex Sid Wilson

Kelly Osbourne isn't holding back as she seemingly hit out at her ex fiancé, and 'former' Slipknot star Sid Wilson, in a number of social media posts.

Osbourne's rant comes just days after it was reported Wilson, 49, had been 'kicked out' of the heavy metal band after more than 25 years. The band or Wilson himself are yet to publicly address the alleged firing.

Now, the daughter of Ozzy and Sharon is having her say.

"Wake the f*** up take some responsibility," she began the string of messages on her Instagram story. "I will not take you s**t anymore. I'm done.

"I want to be happy and I have a beautiful son to raise," she continued, before concluding: "Leave me alone. let me heal. I can’t protect you from yourself anymore."

Wilson and Osbourne got engaged in 2025, but reportedly called off their relationship a year later, with a source saying they had been 'facing challenges in their relationship for some time'.

She continued with the posts, later asking for her 'dogs and all her possessions back,' along with child support.

Elsewhere, Osbourne posted a number of quote posts, with one reading: "My job is to protect my kids, not your feelings, not your expectations."

Another one read: "My son's little heart once beat right inside of mine, so trust me when I say I will protect it at all costs."

Osbourne and Wilson welcomed their son, Sidney, in 2022, four years before their relationship ended.

In another post, Kelly spoke about how 'the loudest defence of the guilty is rarely innocence, it's a distraction'.

The 41-year-old concluded by saying: "This is why I always take accountability! As they say some are sicker than others."

Wilson was not mentioned by name in any of the posts.

UNILAD has contacted representatives of Sid Wilson for comment.

Osbourne and Wilson had been friends since 1999, meeting through Osbourne's late father, Black Sabbath member Ozzy Osbourne.

However, it wasn't until over two decades later, when they began dating in 2022.

Things moved quickly, with the couple announcing the former reality TV star was expecting their first child in May 2022.

Alongside a selfie of herself holding an ultrasound photo, Osbourne penned: "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!"

In Janurary 2023, Sharon Osbourne announced the news of the happy arrival on during an appearance on The Talk.

Two years after the birth of their son, Wilson popped the question, during Ozzy Osbourne's final show with Black Sabbath, which took place at Villa Park in Birmingham, England.

Sadly, the 76-year-old rock legend died just weeks later, with the couple reportedly calling off their engagement the following March.

At the time, sources said the television personality and the rock star were focused on co-parenting their son and 'keeping things amicable' for him.
