Truth behind viral footage showing Sydney Sweeney walking down aisle in wedding dress

A video of Sydney Sweeney walking down an aisle in a wedding dress has done the rounds online, and it's finally been explained.

For those of you clued up on pop culture and celebrity news, you'll probably be well aware of the Anyone but You star's reported split from fiancé Jonathan Davino.

Sweeney and Davino's wedding was scheduled for May this year, but it has since reportedly been called off.

This only fuelled the rumours that the actress had an ongoing fling with her former co-star Glen Powell, though the actor's mother was quick to go public and rubbish these claims.

She called the 27-year-old a 'really, really good friend' to both him and the family, in an attempt shut the noise down.

However, more noise has come from a viral video showing the actress making her way down the aisle in a long, flowing white dress along with matching veil and white heels.

While some social media users thought that Sweeney had moved on from Davino in record time, it looks like this is far from the case.

She looked over the moon to be making the walk, but it turns out it's all for the upcoming third season of HBO's Euphoria.

According to TMZ, the video was taken on the set of the popular TV show, with her character, Cassie, possibly about to marry Nate, played by Jacob Elordi.

In all fairness, if you don't get the special day in real life, why not get one on-screen?

It's been three months since Sweeney ended her long-term relationship, with the actor sharing the highlights of her life on Instagram.

She was even pictured with Powell at his sister's wedding, which didn't help the case that the actor's mother tried so hard to hit back at.

Photos of the two on-set started the rumours, and it hasn't slowed down since, though the pair admitted they leaned into the chatter to promote the film.

Powell told the New York Times last year that they have 'effortless chemistry', but were just 'selling a rom-com'.

“That’s people wanting what’s on the screen off the screen, and sometimes you just have to lean into it a bit — and it worked wonderfully. Sydney is very smart,” he said.

Sweeney explained that she wanted to make public appearances with Powell as a result of the chatter, admitting: "I was on every call. I was in text group chats.

“I wanted to make sure that we were actively having a conversation with the audience as we were promoting this film, because at the end of the day, they’re the ones who created the entire narrative,” she claimed at the time.
