Last night after their duet on the ACM's, Thomas Rhett tweeted out a picture of him and Maren Morris singing on Thomas' new single "Craving You".
And that picture captured a very strange look on Maren Morris' face which she even made fun of by tweeting;
We did it! And this is the most epic expression I've ever pulled. So proud of you, TR!
In fairness to Morris, if you really watch how weird singers' face look when they perform it will make you chuckle a bit. Here are a few more I found on Twitter.
