Cher is warning fans they may never hear her collaboration with Lady Gaga because Gaga "doesn't like" the song.
The ladies teamed up to record a track called "The Greatest Thing," but Cher says it may be left off her upcoming album because of a disagreement between her and Gaga.
When a Twitter follower asked why she hasn't released the song, Cher wrote: "It's done and she doesn't like it, or want it to come out. She's an artist, it's up to her. I'm disappointed too."
