Matthew Modine can add “wedding officiant” to his résumé.

On Wednesday, Oct. 2, a photo of the actor and filmmaker, 65, officiating the wedding of his Stranger Things costar Millie Bobby Brown and her husband Jake Bongiovi was shared by the groom on his Instagram page.

In the image, Modine — who played the role of Dr. Martin Brenner (AKA ‘Papa’) opposite Brown, 20, in the hit Netflix series — wore a black jacket over a white shirt and black pants for the special occasion.

Standing tall under the floral wedding arch, Modine smiled as Bongiovi, 22, read out his vows to his bride during the May wedding.

“Amazing. Who’s the old guy with a beard?? 🤪❤️🍀,” Modine joked in Bongiovi’s comment section afterward.

The pair were also snapped sharing a kiss before a black and white photo featured Bongiovi appearing to get ready.

The proud husband then included a photo of himself standing between his father Jon Bon Jovi and Brown’s father Robert Brown.

“Forever and always, your husband,” Bongiovi wrote in his caption.

Brown also shared a carousel of wedding photos. After including snaps of the couple, she concluded the post with a solo shot of her blowing bubble gum while wearing a chic silk mini-dress.

“Forever and always, your wife,” her caption read.

Romance rumors between Brown and Bongiovi first sparked in June 2021 after he shared a selfie with Brown on Instagram. They were then photographed holding hands in New York City weeks later and by November of 2021 Brown confirmed their relationship by posting a blurry photo of the pair.
