The 'Watermelon Sugar' singer leaned in close to Wilde several times as the group chatted. After Styles and Wilde were seen holding hands at a friend's wedding in Montecito, California, over the weekend, a source confirmed to People Magazine that "they have dated for a few weeks." In this week's issue of People Magazine, on newsstands Friday (local time), sources said Wilde struck up a close friendship with Styles last fall as they began work on her highly-anticipated sophomore directorial project 'Don't Worry Darling', which she also stars in. Kendall Jenner Goes for a Drive in Her Cadillac With Ex-Boyfriend Harry Styles Riding a Bike Beside Her and We Wonder What’s Cooking!

As they spent time together on-and off-set, their friendship "quickly turned romantic," said an insider. "Their chemistry was very obvious," reported People Magazine. "Everyone saw it coming. During breaks, he's hasn't been able to stay away and visited her trailer," the source added. In September, Wilde cast Styles in the movie replacing former lead Shia LaBeouf. Despite their growing relationship, the two continue to keep things "very professional" at work.
