Mariah Carey just threw shade at Arianna Grande and Demi Lovato. The Grammy-award winning diva said when she appeared at a TV show on Sunday that she does not know the "Problem" and the "Skyscraper" singers.

According to Fox News, Mariah played the game "Plead the Fifth" with host Andy Cohen when she appeared at the "Watch What Happens Live". The "Hero" diva was given names of various music artists and had to answer if she knows them or not. And when asked about Arianna and Demi, Mariah said that she does not know them. She also explained that she is not familiar with the "Side to Side" and "Heart Attack" singer since she listens to hip-hop more frequently than pop music.

Mariah said that she does not know Arianna and when asked about Demi, she said that she will not saying anything to the "Heart Attack" singer since she does not know her either. The "Touch My Body" singer also said that Demi should come to her to introduce herself and that's when she should tell her about her opinion. Mariah also added that that's how she should handle it.

Back in June, Demi first threw shade at Mariah defending Arianna Grande when the "Problem" singer was compared to the diva two years ago. Though she admitted that Mariah really is talented and a legend, the "Heart Attack" singer said that the "Hero" singer often disses people. She also said that Mariah really has a talent and may be considered a superhuman because of it but she is unnecessarily rude, as reported by LA Times.

Aside from the two, Mariah was also asked if she knows other artists like. The Grammy-award winning diva said that she has had a nice conversation with Lady Gaga, thinks that Taylor I really sweet, said that Katy Perry is a nice girl, and also said that she loves Britney Spears. The "Hero" singer also said that she might have met Miley Cyrus in a bathroom and has never had the chance to talk to Madonna.
