It's that time of year again: when the POTUS, First Lady and other D.C. bigwigs attend the annual holiday
Christmas in Washington concert. With hosts Dr. Phil and wifey Robin (who even gives you TV Guide users a shout-out), the concert is a musical celebration benefiting the National Children's Medical Center. So who's on the roster? Let's see there's Ne-Yo, Alan Jackson, Andrea Bocelli and Katharine McPhee (talk about a wide assortment). Even
High School Musical celeb Vanessa Hudgens will be doing a little number. Get a peek of her belting out the classic Christmas tune "Angels We Have Heard On High."
