Mariah Carey Takes The Plunge In Red Gown At Rockefeller Christmas Tree Lighting

Christmas is Mariah Carey's favourite holiday, so it's no wonder the 44-year-old songstress wore her most glamourous gown yet when she attended the Rockefeller Christmas tree lighting in New York City.

On Wednesday night, the "Butterfly" singer left us breathless when she went on stage wearing a plunging red sparkling gown and a matching fur capelet.

Sporting oodles of diamond jewelry—including a bib necklace and bangles—dramatic wavy hair and a ton of attitude, Mimi looked the epitome of the iconic diva that she is.

Unfortunately, her performance was lambasted by critics as being one of her worst in recent years. After leaving her fans waiting for three hours, Mariah left them disappointed when she sounded off-key, especially during a rendition of her holiday classic, "All I Want for Christmas."
