A complete timeline of Harry Styles and Olivia Wilde's relationship

The publication reported that LaBeouf exited the project because of a scheduling conflict. But three months later, Variety reported that Wilde fired LaBeouf.

"Though shooting had not started yet when LaBeouf departed, insiders close to the project say LaBeouf displayed poor behavior and his style clashed with the cast and crew, including Wilde, who ultimately fired him," Variety reported in December 2020.

Wilde directed "Don't Worry Darling," which is described as a psychological thriller. The "Booksmart" director also stars in the film and serves as a producer. The star-studded cast includes Florence Pugh, Chris Pine, and Gemma Chan.

Wilde reacted to the casting of Styles and Pugh as Jack and Alice, respectively, by sharing a post on Instagram.

"Very proud to work with these fine folks," she wrote.

Production on "DWD" began in October 2020 but paused in November after a positive COVID-19 test on the set, Deadline reported.

Wilde told the magazine that she was amazed by his "openness and commitment" to Christopher Nolan's movie, which also marked Styles' feature-film debut.

The actress also said that she and "DWD" costume designer Arianne Phillips "did a little victory dance" when Styles signed on for the movie "because we knew that he has a real appreciation for fashion and style."

"And this movie is incredibly stylistic," Wilde said. "It's very heightened and opulent, and I'm really grateful that he is so enthusiastic about that element of the process — some actors just don't care."

Wilde also called Styles "very modern."

"And I hope that this brand of confidence as a male that Harry has — truly devoid of any traces of toxic masculinity — is indicative of his generation and therefore the future of the world," she said.

Wilde added: "It's pretty powerful and kind of extraordinary to see someone in his position redefining what it can mean to be a man with confidence."

News of the breakup emerged the same day that Styles' Vogue cover was released.

"The split happened at the beginning of the year," an anonymous source told People.

Wilde and Sudeikis' engagement was revealed in January 2013. They share a son named Otis and a daughter named Daisy.

"It's been amicable and they've transitioned into a great co-parenting routine," the source told People of the split. "The children are the priority and the heart of the family's relationship."

Owens called it an "outright attack" on "manly men." In response, Wilde tweeted her: "You're pathetic."

Page Six posted a video and plenty of photos of the pair at the wedding in Montecito, California.

"They were affectionate around their friends, held hands and looked very happy," a source told People. "They have dated for a few weeks."

According to TMZ, there were only 16 people in attendance and Styles brought Wilde as his plus-one. Styles officiated the wedding, according to Entertainment Tonight.

A source also told Us Weekly that Styles referred to the actress as his girlfriend during his speech.

Photos published by Daily Mail UK shortly after showed the stars arriving at Styles' LA home with luggage.

They were also seen hanging out in Santa Barbara with some friends around that time.

She posted a black-and-white photo of him in a classic car and gushed about his "humility and grace."

"Little known fact: most male actors don't want to play supporting roles in female-led films," Wilde's caption began. "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."

Wilde said that Styles was a rare actor who didn't mind taking a backseat to Pugh, his on-screen wife.

"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," she said. "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."

Styles won the award for best pop solo performance for "Watermelon Sugar" and the 63rd Grammys. He also performed a jazzy rendition of the hit song at the award show.

That night, Wilde posted an old photo of Paul McCartney biting into a slice of watermelon on her Instagram story. The image was reminiscent of Styles biting into the fruit in his music video for "Watermelon Sugar."

Later that month, Wilde also commented a laughing emoji on a post from writer Evan Ross Katz, who reacted to Styles' portrait for Gucci's "Beloved" campaign and wrote: "Need a cinematic universe where it's Harry Styles and Allison Janney in bulky fur coats. We can figure out plot details at a later date."

According to the Daily Mail, they had a date night in West London in April. Meanwhile, Entertainment Tonight reported that Wilde was keeping Styles company in London as he filmed an upcoming movie called "My Policeman."

Additionally, ET reported that Wilde was in the UK to co-parent with Sudeikis, who was also in the area.

"Olivia is still in London, supporting Harry behind the scenes," a source told Us Weekly in May. "She gets a chance to bond with the cast when they're not filming but is more so excited to spend alone time with Harry when he's off set."

The publication reported that the stars were in a scenic area called Monte Argentario

According to Us Weekly, it was Styles' idea for them to have a getaway before diving back into separate work projects.

"It couldn't be any more romantic," an anonymous source said. "It's been just the two of them and their bodyguards."

Days prior to showing full-on PDA, Styles and Wilde were seen walking through Italy with their arms around each other. They were also spotted dining together and attending the England vs. Ukraine soccer match at Stadio Olimpico in Rome.
