Christmas in Rockefeller Center

Mariah Carey, Prince Royce, Darius Rucker and the Rockettes will join the star-studded holiday special, "Christmas in Rockefeller Center," which initially aired live from Rockefeller Center on Wednesday, December 3. The show is hosted by "Today" anchors Matt Lauer, Savannah Guthrie, Al Roker and Natalie Morales, and features performances from Lady Gaga & Tony Bennett, Cyndi Lauper with Billy Porter, Seth MacFarlane featuring Sara Bareilles, Idina Menzel, Pentatonix, LeAnn Rimes and Trisha Yearwood.

Once again, Green is Universal - NBCUniversal's sustainability initiative - and the Arbor Day Foundation kicked off their tree planting campaign, "Share a Tree," during the "Christmas in Rockefeller Center" broadcast. Viewers were asked to participate by tweeting #shareatree or visiting greenisuniversal.com. For every tweet, like, share or comment, the Arbor Day Foundation will plant one tree, up to one million.
