Olivia Wilde beams on set of ‘Don’t Worry Darling’ after Harry Styles visit

Harry Styles may have fallen for Olivia Wilde on the set of “Don’t Worry Darling,” but the director looks just as smitten as he is.

A photo from early November shows Wilde, 36, dressed in costume and beaming as she greets the former One Direction crooner, 26, at her trailer.

As Page Six exclusively reported, Styles and Wilde fell for each other on the Palm Springs, Calif., set of her new psychological thriller, which also stars Chris Pine and Florence Pugh.

Styles has been introducing Wilde as his girlfriend, and sources told Page Six they were “delighted” to see he brought her as his date to agent Jeffrey Azoff’s wedding.

During filming, Styles holed up at pal James Corden’s residence, where he was able to keep his budding relationship with Wilde under wraps.

Although there’s a 10-year age gap between them, we’re told “Harry doesn’t give a f–k about that sort of thing,” which adds up, as he once said he’d date someone as old as his mother.
