Mariah Carey may have cheated when she sang “All I Want for Christmas is You” at Macy’s Thanksgiving Day Parade. Someone who was there in person posted a TikTok where you can clearly see a big screen with the lyrics scrolling as she sang…

A spokesperson for Macy’s said the screen was there so the audience could sing along . . . but it was never shown during the broadcast, so the argument can be made that they were HIDING it.

There are other explanations, though… Some people on Twitter claim the screen was a failsafe in case Mariah’s in-ear monitor failed, so she didn’t lose her place. Or it could have been for the dancers so they didn’t lose theirs.
