Actress looks unrecognisable as she films American Horror Story – but can you guess who it is?

The stars of American Horror Story were seen on set for the first time on Monday when shooting for the 12th series began.

As the cameras rolled, onlookers’ heads turned as the cast strolled the streets of New York in character.

While Emma Roberts looked instantly recognizable, her co-star looked dramatically different.

The actress rocked a dark wig with heavy bangs and her face was masked by shades of red – but can you guess who it is?

One clue is that this TV star also has a career in fashion modeling and has made a name for herself by walking for the likes of Chanel, Fendi, and Stella McCartney.

Do you know who it is? That’s right! It’s Cara Delevin.

The Hollywood star turned the sidewalk into a catwalk as she strutted around NYC in red platform shoes.

Cara’s Cruelle De Vil-esque persona put an eccentric spin on gothic glamor in the quirky boots and red leather gloves she paired with a pencil skirt and dramatic blazer with ruffled hems.

Her usual blonde hair was gone and replaced by a dark brown wig and a full face with makeup.

When filming began, Cara was pictured smoking from a cigarette holder.

Cara and Emma were shooting scenes for the upcoming entry of Ryan Murphy and Brad Falchuk’s long-running FX anthology, called Delicate.

It is based on Danielle Valentine’s upcoming novel called Delicate Condition.

The book is about a woman who is convinced that someone sinister is preventing her pregnancy from happening.

While it’s Cara’s first time in American Horror Story, Emma previously starred in the franchise from 2013 to 2019 during season three, season four, season seven, and season eight; she played Madison Montgomery, Maggie Esmerelda, Serena Belinda and Brooke Thompson.

But some fans threatened to boycott the show after Kim Kardashian announced she would be joining the cast.

The reality star, 42, posted the surprise news to her Instagram page earlier this month, via the teaser trailer she shared, which was also posted to the official American Horror Story Instagram.

The complaints come despite the fact that American Horror Story has a long history of casting celebrities over the years.

One of Lady Gaga’s first acting roles was the Countess, a blood-sucking vampire in AHS: Hotel.

And the series has also seen guest appearances from supermodel Naomi Campbell, singer Steve Nicks and Maroon 5’s Adam Levine.

Some people defended Kim and said, ‘I’ll give it a try and see what Kim can do. I was pleasantly surprised with Lady Gaga in Hotel, so we’ll see. Glad Emma’s back!’

The ominous clip didn’t depict Kim, but it had eerie music that read, “AHS12. Emma Roberts and Kim Kardashian are delicate. This summer.’

The clip showed a hint of a female figure in the background, but it’s not known if it was supposed to represent her or Emma.

Kim hasn’t revealed in what capacity or if she’s playing herself, but The Hollywood Reporter revealed details shortly after the star shared the announcement.
