Tim McGraw and Faith Hill are timeless to say the least.

They're a diamond that still has their shine, and entertainers are still in the game after decades in country music. Tim and Faith performed at Sunday night's ACM Awards in Vegas a brand-new song called 'Meanwhile Back at Mama's'.

Tim started sitting down in his suit solo on the stage, and Faith Hill came out to help him out in one of the coolest moments of the night.

Here's a throwback to Tim and Faith performing 15 years ago at the ACM Awards. Why do I have a feeling they may end up in the Country Music Hall of Fame? Maybe this will foreshadow another Tim McGraw + Faith Hill tour?
