Niall Horan has revealed he won't be attending his ex-bandmate Harry Styles' wedding, after the singer got engaged to actress Zoë Kravitz.

The One Direction star, 32, is believed to have gotten engaged to the actress, 37, after a whirlwind eight month romance - with Zoë pictured last month with an enormous diamond ring on her wedding finger. 

Niall, 32, was asked about the upcoming nuptials during a recent radio interview, but joked he was 'too busy' to attend Harry's big day.

Speculation surrounding Harry's wedding is mounting with sources saying the couple have been eyeing up locations in the South of France or Italy. 

Questions have repeatedly risen about how friendly relations are between One Direction's stars since they split in 2016, with the band's only appearance together coming when they attended Liam Payne's funeral in October 2024. 

Sources previously told Daily Mail that while Niall is on equable enough terms with Louis Tomlinson and Zayn Malik, all three stars have tensions with Harry.

Speaking on The Edge Breakfast radio show in New Zealand this week, Niall was asked whether he had any 'big events,' such as weddings, in his diary.

The singer said: 'A couple of mates of mine are getting married, so that's going to be very fun.'

Asked whether any of these 'mates' were those he used to work with, Niall caught on to the real meaning of the question, and said: 'All right, no, no, no. I get it now. No, just mates of mine … I am not going, if that's what you're asking.'

The hosts shared their disappointment, before Niall joked: 'I'm a busy man.'

Despite claims of tensions, Niall previously praised Harry's comeback single Aperture, telling Hits Radio: 'I'm delighted for him. Complete like, change of sound but yeah it's a banger, isn't it?'

Zoë recently debuted a stunning diamond on her ring finger during an appearance in Hampstead last month and it was later revealed that Harry proposed to her with a massive sparkler rumoured to cost around $1 million. 

She was previously engaged to actor Channing Tatum, but they ended their relationship in October 2024. Zoe was married to actor Karl Glusman from June 2019 to December 2020. 

The Batman star is said to be drawn to the idea of a summer wedding with ideas around decorations and dresses having also been discussed. 

A source said: 'Zoë 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.'

They added to The Sun: '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.' 

The Daily Mail has contacted Harry Styles' and Zoe Kravitz representatives for comment.
