Harry Styles is reportedly dating Olivia Wilde, the director of his upcoming film "Don't Worry Darling."

According to several media outlets, the pair were seen holding hands at a friend's wedding in Montecito, California over the weekend.

Photos published by Page Six on January 4 show Styles, 26 holding hands while walking alongside Wilde, 36.

Meanwhile, a source told People Magazine that the two "looked very happy" and have been dating "for a few weeks."

The "Watermelon Sugar" singer is starring alongside Florence Pugh in "Don't Worry Darling," an upcoming psychological thriller directed by Wilde, who is also expected to have a supporting role in the film.

Wilde, who directed the teen comedy series "Booksmart" and appeared in films such as "Tron," "The Change Up" and "In Time," is coming off a split from "We're the Millers" star Jason Sudeikis, with whom she has two kids.
