They got together sometime after Olivia and her husband of seven years Jason Sudeikis ended their engagement in November 2020.
The As It Was singer had already been cast in her movie Don’t Worry Darling a few months before, which is presumably how they met.
Over the next few months, they continued being spotted holding hands, kissing and travelling to Italy and England together.
Olivia was his biggest supporter and was often seen at his Love on Tour gigs, a world tour he started in September 2021.
So, why did they split? Read on to find out…
Why did Harry Styles and Olivia Wilde break up?
The pair made a mutual and amicable decision to split as they are both busy doing other things right now.
Multiple sources told People they are “taking a break” from the relationship as the Watermelon Sugar singer is busy touring.
“He’s still touring and is now going abroad. She is focusing on her kids and her work in LA,” one insider told the publication.
Another source added: “Right now, they have different priorities that are keeping them apart.”
They’re still close friends
One insider told People the pair are “still very close friends” and there is no bad blood between them, they have simply chosen to part ways.
As they are taking a break, the couple could rekindle the relationship in the future when they are able to spend more time together.
They recently worked together on Olivia’s thriller movie Don’t Worry Darling, in which Harry plays the lead character Jack.
Released in September 2022, the film follows the story of husband and wife Jack and Alice, played by Florence Pugh, who live in an idealised 1950s American community.
In the experimental town of Victory, men work on a top-secret project, and Alice soon begins to see cracks in her perfect life and uncover something sinister.
Harry and Olivia were ‘more serious than ever’
The breakup certainly comes as a bit of a shock as just six months ago, a source told People they were “more serious than ever”.
“Harry is very smitten,” the insider said. “Olivia has very much brought out his romantic side. He also has tremendous respect for her when it comes to work.”
They added that he would “love to work with her again” and said they always “support each other’s careers” in the “committed relationship”.
The source acknowledged that they both have busy schedules and said they’re always “finding ways to make things work”.
Even in October, another source told People they were “better than ever” whilst “moving forward with their relationship and are happy and thriving”.
However, things obviously changed in the last few months and both of their schedules sadly seem to have made the relationship unsustainable.
