Kelly Osbourne seemingly aims scathing online attack at ex Sid Wilson days after Slipknot ‘fired’ him

Kelly Osbourne has seemingly aimed a series of cryptic messages in the direction of her ex-partner Sid Wilson, urging him to 'take responsibility' and to pay 'child support'.

Wilson, 49, and Osbourne, 41, broke up in March, calling off their engagement after he proposed to her in July 2025 before the tragic death of her dad, Ozzy Osbourne.

This comes right after it was announced the former Slipknot keyboardist was kicked out of the heavy metal band.

Wilson, nor his old bandmates, are yet to comment publicly on the split, with TMZ reporting he was kicked out of the iconic band after 25 years due to alleged mistreatment of his fellow members.

Now, Wilson's ex-fiancée has seemingly lambasted him with a series of pointed messages on her Instagram Story, though she didn't go as far as naming him directly.

What did Kelly Osbourne's cryptic message say?

The first post on Monday (3 August) read: "Strange how the loudest defence of the guilty is rarely innocence … It’s distraction.

“When the mask slips, they don’t face the mirror they throw it at someone else.

“I also heard that when you break a mirror you get 7 years bad luck! Or is that just karma? This is why I always take accountability. As they say some are sicker than others.”

A dig over child support

Osbourne and Wilson share a three-year-old son, Sidney, together and Osbourne went on to write two further posts, appearing to accuse Wilson of not paying towards the child's upbringing but not explicitly naming him in any of the posts.

She wrote: “Wake the f**k up and take some responsibility I will not take your s**t anymore! I’m done. I want to be happy and I have a beautiful son to raise.

"Leave me alone. Let me heal. I can’t protect you from yourself anymore.

"Also while I'm at it can I have my dogs back and all my possessions. Oh yeah, and maybe some child support?"

LADbible has approached Sid Wilson's representatives for comment.

In between her messages, Osbourne also shared inspirational quotes about mums keeping their children safe.

One quote read: “My son’s little heart once beat right beside mine. So trust me when I say … I will protect it all costs."

Another inspirational quote said: “My job is to protect my kids. Not your feelings. Not your expectations. Not judgements I didn’t ask for.

"My responsibility is to protect their wellbeing. Their nervous systems. Their emotional safety. I will choose them every single time. Over anyone. Over anything.”
