If this is true, fans may not be able to handle themselves. On Friday (July 31), Mariah Carey shared a picture of her posing with Justin Bieber, French Montana and Detroit producer Detail, alluding to a collaboration.

"Coming soon," she wrote on the Instagram of them smiling in the studio. French also shared the pic with the same caption. So... coming soon? That means a project, right?

Justin is in the middle of working on his next album, which has been in the works since his "music journals" were released in 2013. Eric Hudson, who worked with Bieber on his free download track "We Were Born For This" in 2014, is also tagged in the photo.

Carey, who is currently in the middle of her Las Vegas residency, also posted a picture with French Montana, tagging even more people, including Joey Arbagey, DJ Suss One and Stella Bulochnikov. Bulochnikov herself posted a pic with French, sharing the mysterious hashtags: "#whyyoumad #disneymagic #bestenergy #imdonebeingagrownup #vatttttt #french #mimi #itsasmash #loveyou." Perhaps one of those hashtags is a song title? After all, "Why you mad" is a lyric from Mimi's recent "Infinity."

Bieber recently teased a new song, "What Do You Mean," out on August 28. Maybe this new collaboration could be something for his upcoming project? Or Mariah's? Oh, the possibilities!

Carey and Bieber were previously featured together on a remix of "All I Want For Christmas Is You."
