Harry Styles secretly kissed Florence Pugh before Olivia Wilde relationship, sparking Don’t Worry Darling feud

The pash is understood to be the real reason Olivia Wilde and Florence Pugh women fell out while filming Don’t Worry Darling.

Harry Styles secretly kissed co-star Florence Pugh on the set of their film — weeks before he began a relationship with the director, Olivia Wilde.

The pash is understood to be the real reason the two women fell out while filming Don’t Worry Darling.

A source told The Sun: “Harry and Florence had chemistry from the off, which translated incredibly well on-screen.

“One night they had a bit of a snog, all very light-hearted and a bit of fun, and that was that.

“It was being gossiped about by a couple of members of production, otherwise no one would have known.

Harry Styles and Florence Pugh in Olivia Wilde's Don't Worry Darling

“Harry was very much single at the time and Florence had separated from Zach Braff, although she’d kept the split quiet to — ironically — avoid headlines.

“There was no cheating or misbehaviour from anyone.

“However, later on, Harry and Olivia started spending more time together — sneaking off for coffees, hanging out in one another’s trailers, and sharing small, routine intimacies.

“It was clear to all they had a real connection. When they were pictured holding hands for the first time, Florence wasn’t too happy.

“There was already tension between the two women and this undoubtedly fanned the flames.

“Although the feud is one of Hollywood’s worst-kept secrets, everyone involved is a professional and things are now cordial.”

Rumours of a rift surfaced in August when it was claimed Little Women star Florence, 26, had fallen out with Olivia, 38, because of her romance with Harry.

However, at the time, Brit Florence was just said to have “deplored their habit of taking private time together in trailers during filming”.

But in her only interview to promote the 1950s-set thriller, she appeared to take aim at Olivia for using an intimate scene in the trailer for the movie.

She said: “When it’s reduced to your sex scenes . . . to watch the most famous man in the world go down on someone . . . it’s not why we do it. It’s not why I’m in this industry.”

Leaked texts in which Shia LaBeouf, who was originally cast in the role Harry later played, appeared to show Olivia disparaging Florence and only added to the tension.

At the movie’s premiere in Venice, Florence skipped a scheduled group interview, arriving just minutes before the screening.

In the US, a nanny for Olivia and her former partner, Ted Lasso star Jason Sudeikis, 47, has claimed there was a fling between the ex-1D star, 28, and Florence.

The nanny, discredited by the estranged couple, said it began a couple of weeks after Harry joined the cast.

She added: “Then Olivia started seeing Harry herself. It was all very quick.”
