Mariah Carey called out for 'lip-syncing' at AMAs performance as fans say there's one 'obvious' sign

People are flocking to social media to bah-humbug Queen of Christmas Mariah Carey.

Mariah Carey took to the stage at the American Music Awards (AMAs) ceremony for its 50th Anniversary Special at LA Center Studios in Los Angeles yesterday (October 6).

The 55-year-old is the recipient of 10 AMAs herself and performed several hits from one special album in particular, however not all viewers were happy.

Ahead of her performance, Carey sat down with the AMAs to reflect on the award's show's 50th anniversary.

She said: "It’s pretty amazing to be a part of the 50th anniversary of the American Music Awards. This was the first awards show I ever was on. Ever since then, I’ve always just been grateful to be a part of all the moments."

Carey started her set with 'Don't Forget About Us' kicking off the celebrations for an anniversary of her own - 2025 marking the 20th year since she released tenth studio album The Emancipation of Mimi (2005).

She told the crowds: "It’s really just an incredible thing that it’s lasted this long."

And then she sung second single from the album titled 'We Belong Together'.

However, whether or not she actually 'sung' the songs live has been questioned by some social media users.

One Twitter user said: "Mariah’s lip syncs are always so noticeable #AMAs50."

"I hate that Mariah has to lip sync now. Her vocals in the 90s were INSANE," another added.

A third commented: "Do y'all think the final part of Mariah’s performance at the AMAs was live?"

UNILAD has contacted Mariah Carey's representatives for comment.

However, other users fiercely defended the singer.

A user wrote: "Waking up and watching Mariah at the AMAs.. the legend that she is."

"FLAWLESS performance Mariah!!" a second commented.

And a third simply resolved: "Man…y’all gotta STOP saying Mariah Carey lip syncs EVERY TIME she performs smh."

Whether Carey lip-synced some of the lyrics or not, maybe she's just not fully defrosted in some viewers' eyes yet?

But she certainly will be in time for her Christmas tour - beginning November 6 until December 17 - alongside the next stretch of her residency.

The singer's Mariah Carey: The Celebration of Mimi residency began earlier this year and the Live in Las Vegas leg of the tour is set to launch on January 31, Carey performing eight shows before the tour concludes on February 15.
