The Rockefeller Tree Lighting Ceremony is finally here and the line-up is more than merry.
Justin Bieber and the Rockettes are just two of the performances to air Wednesday night, Nov. 30, to celebrating the holiday season.
Bieber's performance with Usher is prerecorded. The pop singer will not be at Rockefeller Center on Wednesday.
The holiday special airs on NBC at 8:00 p.m. and will feature other celebrity appearances by the likes of Cee Lo Green and Katherine McPhee.
Also on the bill are Michael Buble and Carole King.
Faith Hill was scheduled to perform, but this will not happen tonight.
Tens of thousands are expected to gather and watch the annual ceremony, which has been a staple in New York City for over 75 years.
Viewers will see the lighting of the 74-foot Norway spruce that was brought to Rockefeller Center. The tree will be decorated with a whopping 30,000 lights, according to The Huffington Post.
The tree was cut down in the small town of Miffinville, Pennsylvania. The first official tree lighting ceremony took place in 1933.
Despite the merriment, a gridlock alert has been issued for New York City due to Wednesday's festivities.
Not only does the day mark the Rockefeller Tree Lighting ceremony, but President Barack Obama is scheduled to visit New York the same night for a series of campaign fundraisers. Security-related street closings are expected to add to the traffic congestion.
