A new celebrity couple alert to start 2021?

Pop singer Harry Styles, 26, and actress Olivia Wilde, 36, have sparked dating rumors after the stars were seen holding hands while attending the wedding of Styles' agent Jeff Azoff.

Styles and Wilde were seen hand-in-hand as they strolled around the wedding venue at the San Ysidro Ranch in Montecito, California.

A source told People that stars stayed by each other’s side throughout the event.

“They were in Montecito, California this weekend for a wedding,” the insider revealed.

“They were affectionate around their friends, held hands, and looked very happy. They have dated for a few weeks.”

Styles and Wilde worked together on the movie “Don't Worry Darling,” which Wilde directed. During an interview with Vogue, Wilde admitted she and designer Arianne Phillips were thrilled when the One Direction singer signed onto the film.

“She and I did a little victory dance when we heard that we officially had Harry in the film because we knew that he has a real appreciation for fashion and style,” Wilde said.

“And this movie is incredibly stylistic. It’s very heightened and opulent, and I’m really grateful that he is so enthusiastic about that element of the process—some actors just don’t care.”

Wilde went on to commend Styles on his gender-fluid fashion sense. “I think he is in many ways championing that, spearheading that,” she said.

“It’s pretty powerful and kind of extraordinary to see someone in his position redefining what it can mean to be a man with confidence.”

Wilde, who gained notice for her role on the TV drama "House," received acclaim for directing the teen comedy "Booksmart."

News of Wilde and Styles’ possible romance comes after Wilde and actor Jason Sudeikis ended their nine-year engagement at the beginning of 2020. Wilde and Sudeikis share two children, son Otis, 6, and daughter Daisy, 4.

Styles was last linked to French-American model Camille Rowe. He has also dated singer Taylor Swift, reality star Kendall Jenner, British model Cara Delevigne, and other Hollywood starlets.
