Sorry Mariah Carey, but lip-syncing is not one of your talents.

Fans were less than impressed with the 44-year-old diva after she was caught lip-syncing during a live concert at the 2015 Jazz and Blues Festival in Jamaica on Friday.

In the YouTube clip, which was filmed by a concertgoer, the "Always Be My Baby" singer seemed unable to keep up with her pre-recorded track. In the video, Carey could be seen holding the microphone and mouthing the wrong words or not singing at all while the track played.

While the Jamaica Observer praised Carey's performance as "one of the best," fans took to the publication's website to slam the reporter's opinion.

"All Mariah did was lip sync.....I guess the crowd was more excited to see Marian perform than to listen for a genuine performance," one person wrote.

"She was lipping all night. At one point she had the mic at her mouth the song was playing and the crowd swear she was singing... She didn't do one live song," another wrote.

Unfortunately, this isn't the diva's first disastrous performance.

Last December, an audio leaked of Carey's unedited vocals from the annual tree lighting ceremony in New York City. The leaked track revealed Carey's struggle to hit the high notes that she is famous for.

Despite the bad performance, Carey is expected to begin her residency at the Colosseum at Caesars Palace in May.
