This Is 1 Musical Collaboration We Did Not See Coming

You might want to take a seat for this one because it looks like Mariah Carey and Justin Bieber may be joining forces once again! The 45-year-old songstress took to Instagram on Thursday and got us all excited when she posted a photo of her with Justin Bieber, French Montana, and music producer Eric Hudson in what looks to be a recording studio. Mariah captioned the photo, "#comingsoon @frenchmontana @ehudmusic @joeyarbagey @justinbieber," leading us to believe she and Justin are working on music together. We must admit, we're majorly excited! Mariah and Justin previously collaborated in 2011, when they released a duet of "All I Want For Christmas Is You." Keep reading to see her post below, and then check out Mariah and Katy Perry hanging out in Las Vegas and the Mariah and 98 Degrees flashback photo that will have you missing the '90s.
