Mariah Carey is facing the heat after she failed to lip-sync her hit single 'Fantasy' at the 2015 Jazz and Blues Festival in Jamaica.
The 45-year-old songstress pretended to sing the song with her microphone and also missed her cue all together while her backing track played joyfully along, Stuff.co.nz reported.
One fan stated that the American singer completely lipped 'Fantasy' and her mouth did not even move.
Another fain asserted that Carey is one of the best but to come to Jamaica and only lip sync and left them totally unimpressed.
