Mariah Carey

Mariah Carey, one of the most popular singers of the last few decades, has a pretty good personal reason to be upset with Ellen. When Carey was on the show in 2008, she and then-husband Nick Cannon were expecting, but did not make it public knowledge. Ellen nevertheless pressured her into revealing that she was pregnant on the show.

Carey has admitted how awkward she was with the incident, saying, “I was extremely uncomfortable with that moment is all I can say.” If Carey revealing the information when she wasn’t prepared to wasn’t enough, she tragically miscarried shortly after her appearance on the show.
