‘Stranger Things’ star Millie Bobby Brown teases potential music collab with Mariah Carey

Could Mariah Carey be working on new music with Millie Bobby Brown? Stranger Things have happened.

The 18-year-old “Enola Holmes” actress teased a potential collaboration with the 5-time Grammy winner during an appearance on “The Tonight Show Starring Jimmy Fallon.”

Speaking to Fallon, Brown revealed she shares an unlikely friendship with the “We Belong Together” hitmaker — much to the host’s surprise.

The “Stranger Things” star, who plays Eleven on the hit Netflix show, said Carey’s children are fans of her character on the show, prompting her to meet them.

After developing a sweet bond with 11-year-old twins Morocco and Monroe, whom Carey shares with ex-husband Nick Cannon, Brown explained what she and the singer get up to during her visits.

“I’ll just go over and we’ll sing together,” she revealed, adding that the pair even sang in Carey’s state-of-the-art studio.

“We have sung together, yeah,” she added before Fallon asked if fans could expect a joint collab.

“Potentially, I don’t know,” she responded, calling Carey “the most talented singer ever.”

“This is the biggest scoop I’ve ever gotten on ‘The Tonight Show.’ I would buy that in two seconds,” Fallon added.

Brown revealed the pair are so close now that she even calls her “Mimi.”

“We texted today. Yeah, she called me today,” the teen said. “The reason is because she grew up in the public eye and we have connected just on so many different levels.”

“I also just love the way she leads her life with so much power and she just has so much knowledge and she’s so wise. She’s just been such an incredible guiding light for me,” she added.
