Rockefeller Center Tree Lighting 2010: Watch LIVE (VIDEO)

One of the most popular annual events at Rockefeller Center is underway: the Rockefeller Center Tree Lighting for 2010.

The Christmas tree lighting ceremony has temporarily taken down the Rockefeller Center website, but you can watch the ceremony live below (or here).

Tonight's ceremony features live performances by Sheryl Crow, Josh Groban, Jessica Simpson, British singer Katherine Jenkins and teen pop star Charice.

Security is tight at the star-studded event. A bomb plot related to a tree lighting ceremony in Oregon caused the NYPD to amp up security for tonight's event, Fox News reports.
