Photos: Malia & Sasha Obama smile as they help dad light the national Christmas tree

Hohoho!!!

President Barack Obama and the first family have lit the national Christmas tree. 

And this time, his daughters Sasha and Malia remembered to smile.

Flanking their father, their mother Michelle, and their maternal grandmother Marian Robinson, the teenagers beamed as they clustered around the light switch just feet away from the White House.

There was no sign of sullenness on Thursday night's event, as the family giggled together and Michelle read from The Night Before Christmas at the event hosted by Tom Hanks and his wife Rita Wilson.

The major musical performances came from singers Patti LaBelle and Steve Miller

In his address, Obama said the national tree is a 'symbol of hope and holiday spirit.' 

He urged Americans to remember members of the U.S. military serving overseas, as well as their families.
