Harry Styles dresses up as a giant NYC rat for final show at MSG while fiancee Zoe Kravitz watches from audience in a plastic takeout bag costume

Harry Styles took to the stage in costume for the final show of his Madison Square Garden residency on Halloween night.

For the spooky holiday on Saturday, the pop star, 32, and his bride-to-be Zoe Kravitz, 37, dressed up in a couple's costume with a New York City theme.

He wore a giant rat get-up while performing, and the actress was spotted in the stands, wearing a plastic takeout bag costume. 

Following up on his Friday show, affectionately dubbed by fans as Harryween Night 1, he also previously dressed up as Elvis Presley, slipping into a skintight, white jumpsuit for the festivities.

He also made a nod to his One Direction days as he recreated his iconic X-Factor audition outfit.  

Meanwhile, Kravitz was standing in the crowd, wearing a devil costume, and watching Styles perform alongside Presley's granddaughter Riley Keough. 

The duo were also joined by Styles' mother Anne Twist and his sister Gemma Styles for the show. 

For Harryween Night 2, he unveiled his follow-up costume by walking onto the stage in a gigantic, fuzzy onesie with rat ears, pink feet and a long tail.

He wore a pair of large sunglasses and left his fans raving as he picked up a guitar while still in costume and performed.

His fiancée was seen greeting fellow concertgoers in the audience and appeared to be giggling as fans took in their hilarious couple's costume.   

She wore a tiny, white minidress in a nylon material and a design plastered across the front akin to a plastic bag. 

She wore black kitten heels and was seen dancing in the crowd with a drink in hand, the same one that displayed the stunning diamond on her ring finger. 

Their display comes as their wedding is on the horizon with ongoing fan speculation about their forthcoming nuptials and what details the couple will incorporate into their celebration. 

Styles and Kravitz have been romantically linked since August 2025. 

In April earlier this year, it was revealed that the singer popped the question as Kravitz was later seen with a bejeweled ring finger during an outing. 

With his show on Saturday night, Styles wrapped his 30-night Madison Square Garden residency in the Big Apple.

During one of his shows in September, he had addressed fans' concerns that he will be retiring after his tour especially as he is preparing to tie the knot with Kravitz.

Less than a week ago, he also released a wedding-themed music video as their speculated wedding date gets closer.  

Earlier this month, reports emerged, seemingly confirming that the couple are planning to marry in an intimate ceremony with just close family and friends present.

The couple's engagement was revealed in April after a whirlwind eight-month romance – with Kravitz pictured with an enormous diamond ring on her wedding finger at the time.

Sources are now claiming that Kravitz and Styles are hoping to tie the knot in a small ceremony, before celebrating with a 'big party' with 'live music.'

The insider added that while Kravitz and Styles are very 'involved' with their respective work schedules, they are taking a very 'laid-back' approach when it comes to planning their wedding.

It was previously reported that the couple are hoping to marry in the UK 'around Christmas time' but have also mulled over the idea of having a second ceremony in New York.

A source said: 'Zoe and Harry want to have live music - that's a big part of the wedding for them.'

They went on to tell People: 'Other than that, they really care most about having their loved ones around and partying with those close to them.

'They're not very fussy when it comes to wedding details. They care more about curating a fun and beautiful experience for those they hold dear.'

Though earlier this year, it was previously reported that Kravitz and Styles were considering 'a small wedding in front of just family and close friends in the UK around Christmas time.'

A source told the publication: 'I know for a fact Zoe would want to do something in New York because of her dad Lenny, so if anything it's going to be two weddings.

'Dad still lives in downtown [Manhattan]. It could be at the Fouquet's Hotel. If she does two [weddings] it would be one in London and one in New York.'

A different source previously told The Sun: 'Zoe is already thinking about the wedding. She wants something unique and has started discussing ideas for outfits, themes and designs.

'She's torn between a very intimate ceremony - possibly even eloping - and a larger celebration with all their loved ones, though a bigger wedding may ultimately win out.'

The insider added: 'She talks about it all the time - beautiful locations like Paris or the French Riviera, lots of flowers, stunning outfits, and a celebration that lasts all day and night, surrounded by love.'
