HARRY Styles secretly kissed co-star Florence Pugh on the set of their film – weeks before he began a relationship with its director, Olivia Wilde.
The snog is understood to be the real reason the two women fell out while filming Don’t Worry Darling.
Last night, a source said: “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.
