After catching word of Jennifer Lopez's recent comments about her on The Wendy Williams Show, Mariah Carey added fuel to their rumored feud when she dropped by Watch What Happens Live on Tuesday night and dissed the singer once again. When Andy Cohen straight up asked Mariah, "Do you know each other?", she frustratedly responded, "No!" The singer then went on to explain herself, adding, "You know what? I'm very forgetful. Apparently, I'm forgetful because I don't remember the fact that it was just like, 'Hi, I'm so and so.'" Watch the video above to see what Mariah says when asked if she thinks Jennifer is cool.
