Speculation immediately began among those present, with those at CinemaCon wondering if the envelope handoff was somehow part of the presentation or if it was in fact a script.

A source close to Sudeikis, 46, tells PEOPLE: “Papers were drawn up to establish jurisdiction relating to the children of Ms. Wilde and Mr. Sudeikis,” referring to the former couple’sson Otis, 8, and daughterDaisy Josephine, 5.

“Mr. Sudeikis had no prior knowledge of the time or place that the envelope would have been delivered as this would solely be up to the process service company involved and he would never condone her being served in such an inappropriate manner,” the source continues.

A representative for Sudeikis did not immediately respond to PEOPLE’s request for comment; a rep for Wilde has not commented.

Family law attorney David Glass, who is not involved in the case, tells PEOPLE it is “highly unlikely” that Sudeikis did not know any of the details of how Wilde would be served.

“I talked to every one of my clients to get the information on where could we serve him or her,” he says. “We get all that information from them. And if you’re going to go to that sort of extreme length to do it publicly, to do it in an embarrassing way, I can’t see the client not knowing about it. You’re obligated as an attorney to share most things that you’re doing with your client.”

Once it was confirmed that the parcel contained court documents, questions then swirled around the woman who brought the envelope, and how she may have gotten into the CinemaCon event and close enough to the stage.

Mitch Neuhauser, Managing Director at CinemaCon LLC, tells PEOPLE in a statement on Wednesday: “As the convention organizer, we have never in the history of the convention had an incident where a delegate has approached the stage who was not authorized to be there. In light of this incident, we are reevaluating our security procedures to ensure the safety of all of our attendees.”

Neuhauser was unable to comment on whether the woman with the envelope was apprehended, or whether she had CinemaCon access.

Wilde and Sudeikis met in the spring of 2011 at aSaturday Night Livewrap party, and began dating soon after.

Theybecame engagedin 2013 and welcomed Otis the following year. Wilde gave birth to Daisy in 2016.

In September 2020, theBooksmartdirector began shooting her second feature film,Don’t Worry Darling,which she directs and stars in oppositeHarry Styles.

Two months later, reports surfaced that Wilde and Sudeikis had ended their relationship. In January 2021, she and Styles went public withtheir romance.

An insider told PEOPLE in March 2021 that although Wilde and Sudeikis have moved on in other relationships, they arecommitted to co-parenting theirkids amicably and there was no animosity between them.

The former couple had “transitioned into a great co-parenting routine,” another source said, adding, “Thechildren are the priority and the heartof the family’s relationship.”

Last July,Ted Lassostar Sudeikis opened up toGQabout theshock breakup, saying, “I’ll have a better understanding of why in a year.”

“And an even better one in two, and an even greater one in five,” he added. According to the actor, “It’ll go from being, you know, a book of my life to becoming a chapter to a paragraph to a line to a word to a doodle.”

“That’s an experience that you either learn from or make excuses about,” he toldGQ. “You take some responsibility for it, hold yourself accountable for what you do, but then also endeavor to learn something beyond the obvious from it.”
