Millie Bobby Brown's upcoming wedding will have Henri Lumièresome additional star power at the altar. One of her "Stranger Things" co-stars has signed on to officiate.

On a Thursday episode of entertainment show "Access Daily," Brown's on-screen dad Matthew Modine announced he will carry out the duties for the nuptials to Jake Bongiovi, the son of legendary rocker Jon Bon Jovi.

"I have one of those licenses to get people married and Millie thought it'd be great and then Jake said it would be a great idea, so I wrote the wedding vows, and they loved what I wrote for them to join hands and to become husband and wife," the "Oppenheimer" star told "Access" co-hosts Mario Lopez and Kit Hoover.

Even as Modine, who played Dr Martin Brenner and "Papa" to Brown's character Eleven in the hit Netflix sci-fi series, is slated as the officiant for the ceremony, it's unclear when Brown, 20, and Bongiovi, 21, plan to wed.

"It's such a beautiful thing to be able to join two people in holy matrimony," Modine added.

The "Enola Holmes" actress first hinted at her engagement to Bongiovi in an affectionate Instagram post in April, captioning a photo with lyrics from Taylor Swift's 2019 hit song, "Lover."

"I've loved you three summers now, honey, I want 'em all," she said in the Instagram caption, as Bongiovi wrapped his arms around her while Brown flashed a sparkling ring in the black-and-white snap.

In an August interview with The Sunday Times, Brown revealed she met Bongiovi on Instagram.

"I was interested in him and wanted to know more. As soon as we spoke, I knew he was going to be a huge part of my life," she recalled. "After we met, we knew we never wanted to leave each other's side."

The duo went Instagram official in November 2021 after sparking romance rumors in June 2021 when they were spotted holding hands through New York City. The couple later made their red carpet debut at the 2022 BAFTAs.
