What is Sharon Osbourne's surprise Lucifer cameo?

The former X Factor judge does have a small role in the second chapter, which focuses on a grizzly murder committed within the confines of a simulated Mars base.

What episode of Lucifer is Sharon Osbourne in?

Sharon Osbourne appears in season five, episode two of Lucifer on Netflix, which is available to stream now.

Listed as a guest star, her name pops up in the credits at around the eight-minute mark, prior to her appearance 11 minutes in, capping off a montage of suspects from the aforementioned Mars base.

Who does Sharon Osbourne play in Lucifer?

Herself of course! Well, a version of herself at least. The Mars base simulation where the murder takes place is open to any super wealthy person with a dream of intergalactic travel.

In the Lucifer universe, Osbourne is apparently one such person, having spent time in the simulated red planet environment with the eventual murder victim.

"Not to speak ill of the dead, but Judy was a bit of a party pooper," Mrs Osbourne tells the LAPD. "We had about five books the entire time we were in there, and she managed to spoil the endings to all of them."

Detective Decker accuses her of biting the head off a bat before stabbing the victim, even whipping out her best Ozzy impression to pack a little more punch into the accusation.

"Actually, that was my husband that bit the head off a bat," Sharon replies, before turning to Lucifer and saying: "By the way, I never managed to thank you for all the things you did for Ozzy... from one prince of darkness to another, right?"

The cameo references an instance in January 1982, when Ozzy Osbourne bit the head off a bat at a rock concert. It's unclear whether the animal was dead or alive, but Ozzy required urgent rabies vaccinations after the show.

For any fans wondering, after denying the crime ("I did not stab her in her sorry space arse"), Sharon Osbourne disappears and is never again mentioned in the episode or the rest of the season.

It's unclear exactly how the role was arranged; either Sharon is a fan of the show and requested a cameo or the showrunners were keen to sneak a celebrity into their space habitat to surprise viewers.

We expect more details to emerge soon, so watch this space.
