Kelly Osbourne looked incredible on Friday night with a dramatic transformation for Halloween.
The daughter of the late rock legend Ozzy Osbourne perfectly encapsulated spooky season with a black cat costume, complete with a cape and matching ears, as she partied the night away at Annabel's Twisted Fairytales Halloween Party in Mayfair.
Kelly, 42, also appeared to be channelling Angelina Jolie's Maleficent, from the 2014 movie of the same name, with her smoky eye and chiselled contouring
She had even drawn a tiny bat under her eye with eyeliner, making sure no detail was spared.

Describing the event, Annabel's wrote on social media: "This Halloween, Annabel’s enters the dark and fantastical world of Twisted Fairytales. Two nights of familiar stories but with wicked characters and unexpected twists."
The front of the celebrity hotspot had even been transformed into a giant pumpkin.

On Saturday morning, Kelly sipped tea at home with her son Sidney, admitting she was feeling "tired" after the spooky bash.
However, her glamorous cat outfit wasn't the only way she has been celebrating Halloween this year.
Welcoming in the holiday, Kelly shared a photograph of herself in the bathtub wearing a witch's hat and encouraging followers to share "what spells, secrets, and spooky adventures have you planned for All Hallows’ Eve?"
"Will you be dancing with the spirits, stirring up trouble, or casting a little magic of your own?" she wrote.
"Whatever your plans, remember… the witching hour is almost upon us."
Kelly opens up after difficult year
In August, the star opened up to HELLO! about moving back to the UK, navigating grief, and the impact of body shaming.
Her father Ozzy died from a heart attack on 22 July 2025, just weeks after performing a historic farewell show with Black Sabbath.
"It's been the hardest year of my life," Kelly told HELLO!. Speaking candidly about her grief, she said: "I'll never be the person I was before my father died… a part of me died, too."
Kelly also faced intense body-shaming in February 2026 after attending the Brit Awards with her mother, Sharon, to accept the posthumous Lifetime Achievement Award on behalf of Ozzy.

"[I have] this incredible team of people I’ve built around me who are not just my friends, because what you'll find when you're grieving is that people don't know how to handle it, and you do lose a lot of friends. But the ones who stick around are the real ones.
"To go through what I had to go through on top of all of that just made it even harder. So I just had to ignore it."
