All eyes on her! Florence posed up a storm as she hit the red carpet 

Harry and Florence reportedly shared an offscreen kiss after developing 'instant chemistry' on the set of Don't Worry Darling - weeks before the One Direction star began a relationship with its married director, Olivia Wilde.

The beleaguered film, in which Styles and Pugh play a married couple, has been overshadowed by a series of controversies both before and after its memorably awkward premiere at the Venice Film Festival in September.

Notably, Pugh failed to acknowledge Wilde on the red carpet following an on-set dispute - thought to be sparked by the actress's discomfort at her director embarking on a very public relationship with Styles while shooting the film on location in Los Angeles.

Sources claim their fall-out stems from the initial chemistry shared by Pugh and her screen husband before he became romantically involved with Wilde.

An insider 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 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.'

Claims: Harry Styles and Florence reportedly shared an offscreen kiss after developing 'instant chemistry' on the set of Don't Worry Darling - weeks before the One Direction star began a relationship with its married director, Olivia Wilde

The insider added that it was clear Harry and Olivia had a real connection and Florence was reportedly unhappy when photos of them holding hands surfaced.

There was already said to be tension between the two women, with Harry and Olivia's burgeoning romance making things worse.

MailOnline has contacted representatives for Styles, Pugh and Wilde for comment.

A report from Page Six in late July claimed that Pugh was upset with Wilde because she was hooking up with leading man Harry Styles during the production — while still engaged to Jason Sudeikis — before they split in November.

'I can tell you for a fact that Flo seeing Olivia and Harry all over each other on set did not go down well as Olivia was still with Jason when she first hooked up with Harry,' the source said.

Pugh was asked by an Italian journalist at the event about what she found 'inspiring' in the film and appeared to make a sly dig at Wilde.

She responded: 'I think it's very very inspiring to see a woman push back and say 'no', and question everything. It's very exciting to see a woman do that on and off camera.'

Asked when she 'says 'no' off camera, Pugh jokingly responded: 'When do I say 'no'? When someone says I can't have cake.'
