Carrie Underwood and her husband Mike Fisher just celebrated their fourth wedding anniversary on June 11 and to make the whole world know how the singer feels about her lover, she decided to post it to Twitter, but something just went terribly wrong.

There is really nothing wrong with voicing out one's happiness through the social media network, but to tag it wrongly to someone, it's quite an epic fail. Some people just couldn't get it why the country singer tweeted her longtime lover with a wrong Twitter handle. To start off with the couple's celebration of their fourth anniversary as husband and wife, the country singer took her time posting a tweet in her Twitter account to greet Fisher, but it went out to be a big mistake.

Carrie Underwood reportedly used a different Twitter handle which she first thought to be of her husband. It seems like the busy work has been consuming the 'American Idol' winner lately as she tend to forget the right account. To correct the seemingly unconscious mistake, the country singer was quick to change it with Fisher's correct Twitter handle.

According to the previous reports, the greeting has been first addressed to @mikefisher which is said to be someone else and that the NHL player. Fisher's right Twitter handle was reported as @mikefisher1212. Carrie Underwood's husband may not be really bothered by the fact that his wife tagged a different account as he quickly responded to his wife's sweet note.

"Hard to believe its 4 years ago today @carrieunderwood and I were married. Best thing I've ever done. I Love her more now than ever!" Mike Fisher tweeted in response.

The sweet exchange of words just signifies that the couple is still into each other and that their vow remains strong. Carrie Underwood and her husband were previously rumored to be on the rocky state of their marriage. When it comes to expanding their family with kids, the couple seems to be not yet ready.
