It seems as though Harry Styles and Olivia Wilde have been leaving hints about their newfound romance.
The pair have been at the centre of dating rumours after being spotted holding hands at Olivia's manager's wedding earlier this week.
It’s believed that Harry and Olivia grew close while shooting the movie, Don’t Worry Darling - so it's fair to say some cast and crew members are shell-shocked by the dating news.
In fact, Harry, 26, and Olivia, 36, had trouble hiding their "obvious chemistry" on the set of the movie.
As they spent time together on-and off-set, their friendship "quickly turned romantic," a source told People. "Their chemistry was very obvious."
And after Harry had been criticised for wearing a dress on a recent magazine cover, Olivia seemed to be the first one to rush to his defence.
"Olivia was going on and on about how wearing a dress still makes Harry masculine," the insider said. "It was again just so obvious she had fallen for him."
The insider also said Harry paid frequent visits to Olivia's trailer during filming.
Despite their budding romance, the two continue to keep things "very professional" at work so that their personal lives don't get in the way of business.
The insider added: "Olivia and Harry created this loving and warm environment. Everyone loved working with them. She takes her work very seriously, but everyone saw it coming."
The Mirror has contacted Harry and Olivia's reps for comment.
The Sign Of The Times singer bagged the highly sought-after role when he was roped in to replace original cast member, Shia LaBeouf.
Directed by Wilde, Don’t Worry Darling is an upcoming psychological film that centres on an unhappy housewife (Florence Pugh) and her picture-perfect husband (Harry Styles), who loves her dearly, but is hiding a dark secret from her.
Olivia broke things off with ex-fiancé Jason Sudeikis after nine years together back in November.
The former couple are left to co-parent their two children - six-year-old son Otis and four-year-old daughter Daisy.
