Timothée Chalamet and Kylie Jenner wore matching sunglasses at ...

Rumours have been swirling for months about a Kylie Jenner and Timothée Chalamet link-up. There were late-night sightings at airports. Tiktok videos of Chalamet's car entering the Hidden Hills oasis where the Kardashian clan reside. Jenner wearing a custom gown by Chalamet's mate Haider Ackermann at the Met Gala in May. The rumour mill was working overtime.

Then, at Beyoncé's Renaissance stop-off in Los Angeles last week, 27-year old Chalamet and Jenner confirmed their romance with an embrace and a liddle kiss for the entire 50,000-strong audience to see. Following that, they attended a New York Fashion Week dinner to mark the inaugural collaboration between Ackermann and skincare wizard Augustinus Bader. So far, so official.

Yesterday the cosmetics mogul and Wonka actor continued on their run of public outings. The pair attended the US Open in New York City, and they fully cemented their love for one another. How? Not just by kisses caught on camera, but by wearing kinda matching fits. Jenner kept things casual in jeans and a tee, while Chalamet wore a hoodie and grey slacks. And both wore blacked-out '90s-adjacent sunnies: Jenner in a pair of her go-to Bottega Veneta shades and Chalamet in Celine. The outfits didn't do a lot, but they said a lot. Because matching sunnies must mean love, right?

Couples dressing together isn't a new phenomenon. But it's definitely the done thing for any new couple who want to really underpin the new commitment – and the Kardashian-Jenners are experts at it. Earlier this year Kendall Jenner and Bad Bunny apparently confirmed their relationship in matching snakeskin boots. Kourtney Kardashian and Travis Barker get down in his ‘n’ hers Dolce and Gabbana, or matching band tees. Kim Kardashian historically synced up with ex-husband Kanye in all sorts of fits.

Chalamet and Jenner haven't actually officially confirmed anything. But maybe they don't need to – the sunnies might've said it instead.
