Olivia Wilde served custody papers on the CinemaCon stage; documents related to the battle for children with ex Jason Sudeikis

LAS VEGAS — The custody battle between actors Olivia Wilde and Jason Sudeikis erupted into the public sphere on Tuesday when Wilde received papers while speaking onstage in front of a large crowd at a film conference.

The “Booksmart” actress and director received an envelope while promoting her new movie, “Don’t Worry Darling,” at CinemaCon, a convention for movie exhibitors held annually in Las Vegas.

Photos from the event reveal Wilde looking surprised upon discovering the contents of the envelope, which were allegedly court documents filed by ex-fiancé Sudeikis regarding custody of their two children.

Wilde ended her seven-year relationship with the “Ted Lasso” at the end of 2020 and soon after began dating one of her new film’s co-stars, Harry Styles.

Variety reported that Sudeikis “had no prior knowledge” of where and when these documents would be delivered.

Sources told the magazine that he would “never tolerate her being served in such an inappropriate way”.

“Usually it’s a type of service that can be done lawyer-to-lawyer or signed,” Samantha Bley DeJean, a divorce lawyer, told ABC News. “To have such a public display – if it’s a mistake, it’s a big mistake. And if it’s on purpose, it’s a statement.”

CinemaCon did not respond to ABC News’ request for comment.
