The weekend marked two festive occasions for the Osbourne clan.
While Halloween celebrations were taking place across the world on Saturday, it was also Kelly Osbourne's birthday - leading her to throw a double-event in Los Angeles.
The reality star celebrated her 34th in style at Mr Chow's restaurant, making a grand arrival in costume as Myrtle Snow from American Horror Story's third season Coven, and current eighth season, Apocalypse.
She copied the iconic character's look by, naturally, donning an over-sized frizzy orange wig.
She added red-rimmed glasses over her ayes and wore a satin mauve wrap-around gown, in the style of notably-eccentric witch Myrtle.
She wore black lace gloves and a black heels to complete the ensemble and painted her complexion with a pale white foundation and a pop of bright red lipstick.
The entire Osbourne clan were present for the evening out, with mum and dad Sharon and Ozzy holding hands as they stepped out.
The couple kept things typically gothic, in-keeping with the theme of the night, as Sharon, 66, donned a sweeping velvet robe in midnight blue, with a paisley mustard print lining it.
She kept things black beneath, and adorned the look with silver necklaces.
Sharon wore her red bobbed 'do in a side parting and she kept make-up fresh and classic.
Ozzy, 69, was in all-black, as usual, with circular shades covering his eyes and his long dark hair worn loosely around his shoulders.
He had a black blazer on and was seen chewing his thumb - which was recently infected to the degree his life was in danger.
Recently-divorced brother Jack, 32, looked to be a Bruce Wayne/Batman hybrid, stepping out in a black suit and tie with a Batman mask on.
Jack was joined by a pink-haired companion, who onlookers believed to be a new romance - despite then-wife Lisa Stelly filing for divorce in May of this year.
Kelly was also joined by a mystery man, dressed in ripped jeans, cowboy boots and a leather jacket - also thought to be a potential new love.
She hired a cross-dresser to attend the event, who came dressed as the birthday girl herself.
