Mariah Carey
The Carey-Lopez animosity has lasted a long time, beginning in the early 2000s when Mariah dared to tell a German reporter her genuine opinions about J-Lo, stating four words: “I don’t know her.” Since then, it appears that both Mariah and Jennifer have been unsure whether they like each other or not. When Andy Cohen asked Lopez about Mariah in 2014, she replied, “I would love to meet her and I would love to be friends with her.”
