Olivia Wilde breaks silence on rumoured boyfriend Harry Styles

Olivia Wilde has turned heads and raised a few eyebrows after her latest Instagram post where she praises Harry Styles - aka her rumoured new boyfriend.

The actress split up with her ex fiancé Jason Sudeikis last year and the pair are reportedly focusing on "coparenting" their children.

Fast forward a few months and it appears that Olivia, 36, and Harry, 27, have become pretty close while working on the movie Don't Worry Darling.

Taking to Instagram to post a black and white candid photo of Harry sitting in a convertible staring into the unknown, Olivia wrote, "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 then went on to throw praise to her new rumoured boyfriend, "Enter: @harrystyles, our 'Jack' . 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. 👊#dontworrydarling."

What a star!

Olivia directed the upcoming film Don't Worry Darling, and is joined by Harry's appearance in the movie.

And according to a source, the couple hit it off after Harry signed up to appear in the upcoming film.
