Carrie Underwood tweeted one giant oops over the weekend.

The country star just celebrated her four-year anniversary with husband Mike Fisher and tweeted him some loving words for the occasion.

The only problem?

Carrie tagged the wrong Mike Fisher in the post.

A fan quickly called Carrie out for tweeting @MikeFisher instead of @MikeFisher1212, her husband’s verified account.

The good news is she quickly deleted that post, following it up with one mentioning Mike’s actual Twitter handle.

Carrie and Mike were married July 10, 2010 at the Ritz Carlton Reynolds Plantation in Georgia in front of 250 close friends and family.
