Harry Styles is keeping mum on his personal relationship with Olivia Wilde, but is singing her praises about her work on the set of their movie Don't Worry Darling.

In an interview with Howard Stern for the latter's SiriusXM show Wednesday, Styles, 28, was asked point-blank by the shock jock, "You fell in love on a movie set?"

"Oh, wow, how to answer this question?" the actor and singer answered slowly. "I had a wonderful experience being directed by Olivia. I think there is something that obviously … acting is very uncomfortable at times. I think you have to trust a lot."

He also noted, "Being able to trust your director is a gift."

"That was very helpful, and it really meant for a really nice experience working on that movie," Styles said.
