"Stranger Things" star Millie Bobby Brown might be collaborating with Grammy award-winning singer Mariah Carey on an undisclosed project. 

The Netflix actress hinted at the potential collaboration during an episode of "The Tonight Show Starring Jimmy Fallon." Brown, 18, appeared on the show to promote her upcoming mystery thriller film "Enola Holmes 2."

Brown revealed she and Carey had developed a friendship because Carey's children are fans of Brown's character Eleven on "Stranger Things." 

After meeting Carey's 11-year-old twins, Morocco and Monroe, the two allegedly started singing songs together in Carey's home studio.
