Los Angeles: Some fans of pop diva Mariah Carey have accused her of lip-syncing and ridiculed her on Twitter.
Carey, 45, performed at Macy's Thanksgiving Day Parade on November 26 and she sang her holiday anthem "All I Want Is Christmas Is You" as she rode a float through the New York City streets, reported Ace Showbiz.
"Turned to the parade just in time to see the Marching Illini play and Mariah Carey lip sync," wrote a fan.
"This thanksgiving I'm thankful that Mariah Carey decided to lip sync at the Macy's parade," another fan sarcastically wrote.
"Thank goodness Mariah Carey got to lip sync today because we all know that voice isn't what it used to be," another added.
Carey was not the only one being accused of faking her performance at the annual parade. Some people also slammed Chris Daughtry after they spotted him lip-syncing his "Long Live Rock and Roll".
