Mariah Carey has angered fans after she supposedly lip synced her Macy's Thanksgiving Day Parade performance.
The 'All I Want For Christmas Is You' singer was slammed for putting on a "low-energy" performance as fans all over America tuned in to watch the annual parade.
The 52-year-old was also accused of forgetting the words to her own festive song, despite being the unofficial 'Queen of Christmas'.
