When Thomas Rhett took the stage at Wednesday night's CMT Awards to sing his hit duet with Maren Morris, one obvious thing was missing -- Morris.

Fans quickly took to Twitter to ask why Rhett performed "Craving You" solo.

While Morris' name was not listed as a performer for the awards show, she has two scheduled shows in Nashville Thursday and Friday for CMA Fest.

Her absence was not explained prior to Rhett's performance and a rep for Morris did not immediately return Fox News' request for comment.
