Mariah Carey is telling the world it will have to wait a little longer to hear her duet with Michael Jackson. At least until his estate is ready to release it.

"It's not in the vault, it's right there, but there is an issue with his estate," the singer told Andy Cohen recently on Watch What Happens Live.
