Olivia Wilde is currently wrapping up her directing role on Don’t Worry Darling, which stars Florence Pugh alongside her rumored new boyfriend Harry Styles.

She gushed over her on-set experience with the 27-year-old “Adore You” singer in a sweet Instagram post on Monday (Feb. 15), which featured a black-and-white photo of Styles in a vintage convertible.

“Little known fact: most male actors don’t want to play supporting roles in female-led films. The industry has raised them to believe it lessens their power (i.e financial value) to accept these roles, which is one of the reasons it’s so hard to get financing for movies focusing on female stories,” she captioned the snap. “No joke, it is harrrrrd to find actors who recognize why it might be worth it to allow for a woman to hold the spotlight.”

Enter: @harrystyles, our ‘Jack,’” Wilde continued. “Not only did he relish the opportunity to allow for the brilliant @florencepugh to hold center stage as our ‘Alice’, but he infused every scene with a nuanced sense of humanity. He didn’t have to join our circus, but he jumped on board with humility and grace, and blew us away every day with his talent, warmth, and ability to drive backwards.”

See the post hereDon’t Worry Darling takes place in the 1950s and stars Pugh as a housewife who discovers an upsetting truth. Styles plays her husband.

The heart-melting post comes about a month after Wilde joined Styles to attend his manager Jeffrey Azoff’s wedding. In photos shared by Page Six, the “Watermelon Sugar” singer arrived in a sleek black suit and a ribbon tie, holding hands with Wilde, who stunned in a flowing floral dress and pink head wrap. Both were staying safe in black face masks.
