What’s in a name? For Millie Bobby Brown… not Bobby, weirdly!

The Stranger Things star dropped a Millie Bobby bombshell about her actual middle name during an interview with Buzzfeed UK alongside her Electric State costar Chris Pratt.

“My middle name is Bonnie,” Brown said.

Pratt tried to clarify the actress’ full name. “Millie Bobby Bonnie Brown?” he asked.

“No, it’s no Bobby. It’s Millie Bonnie Brown,” she responded. “I’ve never told anyone that. You heard it here first!”

Pratt, flabbergasted, asked, “Your middle name is Bonnie? But you just changed it to Bobby for—”

Brown cut him off. “S—s and giggles!” she said.

Pratt then finished his thought. “For your stage name?”

Brown confirmed, “Yup!”

Of course, Brown’s recent marriage to Jake Bongiovi (the son of Jon Bon Jovi) further complicates her name, as she implied that she’d taken her husband’s surname in an Instagram post in August. But the name in the post was “Millie Bobby Brown Bongiovi,” suggesting she’s not dropping her original last name.

Given those two successive revelations, it seems that the actress’ full legal name is now Millie Bonnie Brown Bongiovi. Entertainment Weekly has reached out to representatives for Brown for clarification.

Brown wrapped the final season of Stranger Things in December, and commemorated the milestone with an emotional Instagram post. “Isn’t graduation supposed to bring relief, like you’re glad to leave behind the teachers and classmates? Not me,” she said in a video. “I am nowhere near ready to leave you guys. I love each and every one of you and I’ll forever carry the memories and bonds we’ve created together as a family.”

Brown also told EW that she was excited by the opportunity to improvise dialogue while shooting The Electric State with Pratt. “I typically stick to the script,” she said. “So many times on set, we’d start the scene and just see where it would go. And I had to learn quickly to match Chris’ energy and reciprocate that, so it taught me a lot. He’s probably the funniest person I’ve ever met…it’s been really nice going toe-to-toe with him. Most days, I just laugh from start to finish.”
