The controversy surrounding Olivia Wilde and Florence Pugh’s film “Don’t Worry Darling” has thrust them into the spotlight.

Olivia, who also directs, co-stars with Harry Styles, Chris Pine, and Gemma Chan in the film.

But it’s now clear why Florence Pugh “hates” her film director so much.

The former nanny of Olivia Wilde and Jason Sudeikis’ children spoke out to the Daily Mail about a week ago.

Harry Styles had a romance with Florence Pugh before dating the “Book Smart” director, according to Erika Gerano, mentioned by Page Six and TMZ.

“Flo was f-king Harry and she had a boyfriend,” she told the outlet.

In August of this year, the “Midsommar” actress split from her long-term boyfriend, Zach Braff.

Florence was previously said to be uncomfortable with Olivia flirting with the “Watermelon Sugar” singer because she was still in a committed relationship with Jason Sudeikis.

A source told Page Six during that time:

“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.”

Olivia continued to praise Florence for “Don’t Worry Darling” throughout the press interviews, dismissing any animosity between them and adding that the reports are “untruths.”

Meanwhile, another source claims that Jason Sudeikis discovered Olivia’s romance with the British singer after leaving an Apple Watch behind.

According to the former nanny, when the “Ted Lasso” actor read Olivia and Harry’s raunchy texts, he burst into tears.

She claimed it happened on November 9th, following her return from a weekend off, and she was:

“crying a lot. He had no idea what had happened.”

“After we got the kids ready, Jason went upstairs for coffee. He was crying and all messed up, saying, ‘She left us. She left us!'”

Those who worked at Jason Sudeikis and Olivia Wilde’s shared home forbade them from listening to the “As It Was” singer’s music after discovering she cheated on him with Harry Styles.

Despite the nanny’s numerous claims, Olivia and Jason issued a joint statement calling her claims “false and scabrous,” adding that Erika has been orchestrating an “18-month campaign of harassment.”

They said in a statement:

“We will remain focused on raising and protecting our children in the sincere hope that she will now decide to leave our family alone.”
