Aaron Paul and his wife have officially succeeded in adopting Eleven from 'Stranger Things'

Aaron Paul is officially a dad! Well, sort of.

The Breaking Bad star -- who certainly hasn't been shy about his obsession with Netflix's Stranger Things -- has been joking all summer about adopting Millie Bobby Brown (the 12-year-old actress who portrays Eleven) with his wife, Lauren. On Thursday, the adorable trio finally met, and it was as glorious as you'd imagine.

During Aaron's guest appearance on The Tonight Show Starring Jimmy Fallon last week, he told the 41-year-old host he and his wife are actually "obsessed" with all the kids that star in the '80s-inspired series.

"Oh my god, those kids!" he said. "I love 'em, I'm obsessed with them!"

"They're coming on the show?" he exclaimed, when Jimmy informed him he was having them on in an upcoming episode. "When? Soon? Can I come? I would love to come! I'm obsessed."

Aaron then continued to gush over Millie, telling the story of how he got to interview her for Elle magazine.

"I was asked to interview her and I was terrified," he admitted. "I went to Twitter and confessed my love for [show creators] the Duffer Brothers, and I'm like, 'Dear Duffer Brothers, thank you, sincerely, everyone.' And then Elle reached out and said, 'Hey, would you like to interview Eleven?'"

"I said instantly, 'yes!'" he continued. "She's the best. She's the best! But I was so terrified. She was on a family vacation in Spain and I'm like, 'I got to make this good.'"

Aaron admitted he was a little starstruck, but made it work. "It was great," he said. "My wife and I said that we would want to adopt her. She said that, you know, we could."

It doesn't get much cuter than that!
