Jennifer Lawrence Sings, Hosts, is Totally Awesome on The Late Show: Watch!

by at .  Updated at .

Jennifer Lawrence was a guest on The Late Show with David Letterman last night.

The actress was on hand to promote The Hunger Games: Mockingjay - Part 1, but she might as well have been there to promote herself as the most awesome celebrity alive.

First, J. Law made fun of her singing voice, teaming with Letterman for the worst Christmas duet in recorded history:

Then, Letterman moved on to the Mockingjay trailer and how one scene from it reminds him of a 7-10 bowling split.

Lawrence wasn't sure what he was talking about... and then the producers couldn't cue up an example of it or a sneak peek at the star's new movie... so Lawrence and Letterman got up and walked away!

When they returned, Lawrence found herself behind the hosting desk, finally introducing a clip from The Hunger Games: Mockingjay - Part 1.

Simply amazing all around.

We don't know if you're actually back together with Jennifer Lawrence, Chris Martin. But if you are not, we have one simple question for you:

WHY NOT?!?

In case you weren't aware, there are many reasons why you should love Jennifer Lawrence...
