Katharine McPhee and David Foster performed tracks off their ‘Christmas Songs’ album as hosts of the 22nd Annual Tree Lighting Celebration at The Grove in LA.

They also invited Lacey Chabert, Jonathan Bennett, Kings Return, Mario Lopez and of course… Santa Clause on stage.

David Foster started the show with his “Carol of the Bells” and then introduced Katharine on stage.
