Have a holly jolly Christmas, and in case you didn’t hear, oh my golly Idina Menzel has a holiday album out! The If/Then supernova was among the stars to celebrate the 82nd annual Rockefeller Center Tree Lighting on December 3. Check out the clip below as she performs “Holly Jolly Christmas,” which is also available on her Holiday Wishes. And look out for fellow If/Then fave Tamika Lawrence singing backup! Nothing says “Merry Christmas” like belting around a giant tree.
