Los Angeles, Apr 28 (IANS): Hollywood star Jason Sudeikis "had no prior knowledge" that his former fiance Olivia Wilde, would be served with child custody documents during her appearance at CinemaCon.

"Papers were drawn up to establish jurisdiction relating to the children of Ms. Wilde and Mr. Sudeikis," a source said, reports 'Variety'.

"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."

On Tuesday, while Wilde was presenting the trailer for her new film 'Don't Worry Darling' at the movie exhibitors convention, a mysterious manila envelope labelled "personal and confidential" was slid to her by someone in front of the stage.

At first, onlookers believed the envelope to be a script from someone attempting to gain the 'Booksmart' director's attention, but Deadline reported on Wednesday afternoon that the envelope contained custody documents from Sudeikis.

Variety spoke to several witnesses who said the individual who served Wilde the envelope was credentialed by CinemaCon.

In response to the incident, CinemaCon said in a statement that it would "reevaluate" their security protocols.

"To protect the integrity of our studio partners and the talent, we will reevaluate our security protocols," head of CinemaCon Mitch Neuhauser told 'Variety'.

"We will act accordingly because it's the right thing to do. We want to do the safe, proper thing."

Wilde and Sudeikis were formerly engaged but ended their romantic relationship in 2020, reports 'Variety'.

They share two children together. Wilde is now romantically involved with pop star Harry Styles, one of the leads of 'Don't Worry Darling'.

The clip from 'Don't Worry Darling' certainly turned heads at CinemaCon, as it showed Styles and co-star Florence Pugh engaging in sexual acts on a dining room table.

Despite opening the envelope on stage, Wilde didn't flinch during her presentation, continuing to tell the audience that her film is "a love letter to movies that push the boundaries of our imagination".
