The Rockefeller Christmas tree will be lit tonight for the holiday season.

NBC will broadcast the 81st annual tree lighting live from 8 to 9 p.m. during a ceremony hosted by the "Today" show anchors.

It will feature performances by Mary J. Blige, Maria Carey and The Rockettes, among others.

NBC said the 76-foot Norway spruce will be illuminated with 45,000 multicolored LED lights and will be topped with a 9.5-foot-wide Swarovski crystal star.
