Exes Miranda Lambert and Blake Shelton both perform at ACM Honors

Miranda Lambert and Blake Shelton awkwardly avoided each other at Tuesday night's 10th Annual ACM Honor Awards in Nashville, Tennessee.

The country superstars both performed at the award show but neither walked the red carpet.

Lambert performed after accepting the first-ever Merle Haggard Spirit Award which recognizes "uncompromising artists in the spirit of Merle Haggard, while acknowledging a man who has figured prominently in ACM history."

Shelton also took the stage with fellow country singers Toby Keith, Keith Urban and Dierks Bentley.

Neither Lambert's beau Anderson East or Shelton's girlfriend Gwen Stefani were spotted at the event.

The taped show will air September 9 on CBS.
