It was a stunning moment when actress and director Olivia Wilde was blindsided by a process server at a major entertainment industry event. Wilde was debuting the trailer for the new movie she directed, “Don’t Worry Darling,” starring her new boyfriend Harry Styles, when a process server in the CinemaCon audience stood up and handed Wilde an envelope marked “personal and confidential.” Inside were child custody papers, according to a source, from ex-fiance Jason Sudeikis.
