Taylor Swift joined up with Ryan Reynolds and Blake Lively to go trick-or-treating in Manhattan’s West Village on Sunday for Halloween.

The songstress, 31, was well disguised in a vast squirrel costume, that she unveiled on social media earlier in the day alongside a caption reading: ‘Can’t talk right now, I’m doin hot squirrel s***’ with an emoji of a squirrel.

Her superstar pal Blake meanwhile went for an edgy ensemble which made her look like a black and white character, thanks to clever make-up.

She wore a face mask and had a purse while carrying an orange tote bag that looked like a pumpkin.

‘I didn’t have a costume,’ she said. ‘But I did have gray face paint, a black wig and a crazy idea. Luckily when I googled it, somebody named @hellosharonfarrell already had the same idea.’

She continued, ‘Thanks for being my first YouTube beauty tutorial. I only had 10 mins and thanks to your awesome instructions I pulled it off. Yes I’m covering my boobs with a wig. Don’t we all? No? No??!’

The Rhythm Section star added a number of shots of the ensemble, posing in one shot in which she wrote, ‘Spamming my makeup because I’m proud;’ in another she wrote, ‘How freaky in real life. It tripped people out.’

Taylor’s kooky costume meanwhile sparked further theories about her current work projects among fans on Sunday.

While the look was seemingly innocent to some, others took the look as a hint at an upcoming release, as many speculated that she was alluding to her re-recorded video for her 2012 song We Are Never Getting Back Together.

It was revealed last year that Taylor would be re-recording all of her albums following a massive public fall-out with Scooter Braun and her former label, Big Machine, and she now seems to be hinting at her work via Halloween.

Her group of Swifties delighted in the costume as Twitter went wild, but a majority thought there was a larger meaning to the seemingly innocent ensemble.

On Sunday October 24, New York based social media users captured a filming notice for a project titled ‘Acorn’ that shot on Swift’s street.

One fan account additionally captured images of production equipment being loaded into her apartment.

Some users thought that she may have been shooting a new music video to accompany her upcoming re-recorded album Red, as users pointed out she wore squirrel pajamas in her video for We Are Never Ever Getting Back Together.

Additionally in the video she danced around accompanied by a band wearing furry animal costumes, one of which was a squirrel.
