No lmao. Her performing for fun while she's on vacation is not like her singing a song at her concerts, which she still does very well. Stop trying to undermine her. Side note, 90's Mariah had many bad performances.
I commented on that video on facebook, tagging one of my friends saying "wtf happened to her tone" etc etc, and all of these lambs started attacking me saying "let's see u sing like that after 26 years!1!!1" "She has nodules dont u know!11!!!"
