Brooks wasn't the only one impressed by Fisher's performance. In fact, his Twitter invitation generated comments from hundreds of his followers — including one very special one.

Buried in the 300 or so comments on Brooks’ offer is a simple comment from Underwood’s official Instagram account: “He’s in.”

We don't know about you, but this is one duet we can't wait to see! Who knows, maybe Underwood and her hubby will team up for a duet of their own. They'd certainly make a beautiful power couple!
