Lights, camera, Justin Bieber. Christmas has come to Rockefeller Center.
The traditional tree-lighting ceremony, the 79th annual, in the midtown Manhattan destination was a cautiously paced, all-star event Wednesday night, with carols delivered by the likes of Bieber, who essentially headlined the event, Michael Bublé (singing “I’ll Be Home for Christmas”), Cee Lo Green, Neil Diamond, Carole King, Katharine McPhee and Tony Bennett (the traditional “White Christmas”).
Mariah Carey was also seen in a debut video duet with Bieber, for her “All I Want for Christmas.” The number resembled a big-budget department-store commercial, although the video’s quick cuts made it difficult to determine whether the duo and their singers and dancers were actually in Macy’s or Lord & Taylor.
