The thrill is gone! Now that they've finished shooting their upcoming film, Don't Worry Darling, friends are concerned that Harry Styles and Olivia Wilde's hot romance is fizzling out, a source tells OK!.
"They're starting to realize that they don't have much in common, and a lot of it's because of their age gap," spills the source. "They like different music and food, and their style is opposite too."
Wilde, 37, raised eyebrows when she was spotted earlier this month looking downcast during a solo walk in London, where the singer, 27, is working on a new movie.
"Harry's busy with the project, and Olivia spends a lot of her time with her kids [Otis, 7, and Daisy, 4]," explains the source, noting their dad, Jason Sudeikis, is in town filming Ted Lasso.
"Harry and Olivia have agreed to reassess their relationship once they're back in L.A.," the source adds. "They still care deeply for one another, but maybe this romance wasn't meant to go beyond the set."
With the Rush star and the "Watermelon Sugar" crooner cooling off, perhaps the timing is right for Sudeikis to re-enter the picture. As OK! previously reported, the SNL alum has been "in a world of pain," since his breakup with the actress.
While he continues holds out hopes for a reconciliation with Wilde, Sudeikis hasn't been too lonely. OK! previously learned that he had been hanging out with British model Keeley Hazell and she has been there to "pick up the pieces" of his broken heart.
"He always found Keeley incredibly attractive," an insider adds.
