London: Singer Demi Lovato says she dislikes the way pop star Mariah Carey's "constantly disses" people.
The 23-year-old American singer has slammed the "Hero" hitmaker, saying her comments about other musicians are nasty, reported Female First.
Lovato shared her views of the 46-year-old powerhouse on social media when she commented on a meme, which paralleled Mariah to Ariana Grande, 22, with the caption "When you order it online vs when it arrives".
Lovato wrote underneath the post, "You got it the wrong way around honey (sic)."
"Mariah is a legend and is so talented but constantly disses people. It's nasty the way she treats Jennifer. Ari did nothing wrong. (sic)."
Carey previously claimed she didn't know who Jennifer Lopez was and had never met the "Ain't Your Mama" musician.
