Running up that altar.
Millie Bobby Brown’s onscreen “Stranger Things” father, Matthew Modine, will officiate her upcoming wedding to Jake Bongiovi.
The 64-year-old “Full Metal Jacket” alum confirmed the news during an appearance on “Access Hollywood” Thursday.
“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,” he explained.

Modine, who’s been married for 44 years to actress Caridad Rivera, added, “It’s such a beautiful thing to be able to join two people in holy matrimony.”
The “Oppenheimer” star revealed he officiated only one other wedding ceremony during the COVID-19 pandemic in upstate New York, which was outside and “weird.”
Modine and Brown have worked together since Season 1 of “Stranger Things” in 2016. He revealed on “The Jonathan Ross Show” in 2022 that he felt “protective” of her.
“Over the course of my career, the young actors and actresses whose lives were destroyed by that kind of fame and money and everything. It can be very destructive and disorienting,” Modine explained. “I just wanted to do everything I could to make sure she was safe and she understood that a career is a roller coaster, that there’s ups and downs to it.”
While Brown, 20, and rocker Jon Bon Jovi’s son have yet to announce a wedding date of their own, the Florence by Mills founder joked about shaving her head for her big day like her “Stranger Things” character, Eleven.

She slyly added in an interview with MTV that Modine, her “fake dad,” would officiate their nuptials, but seemingly as a joke at the time.
When asked which of her cast mates would be the ring bearer, Brown replied, “Noah [Schnapp]. Obviously.”
The Post has contacted reps for Brown and Schnapp for comment.

Brown and Bongiovi, 21, started dating in 2021 and in June, he proposed to the “Damsel” star underwater during a diving excursion — where they almost lost the ring.
“As I go to show him, the ring falls off my finger, plummets so fast it was like a cinematic movie,” Brown told Jimmy Fallon earlier this month about the sentimental sparkler.
She continued, “Jake throws himself so deep—the diver was like, ‘You can’t do that, your ears, literally your brain will explode,’ — he throws himself, he does a cinematic, like, grab, opens and saved the ring.”

“I truly feel like it’s a reflection of who he is and I feel like we are always gonna have each other’s back and if anyone drops the ball, we got it,” Brown gushed.
The fifth and final season of “Stranger Things” started production in January and is set for a Netflix 2025 release.
