Grumpy Cat has taken the internet by storm and it seems like she is popping up everywhere.

The mean mugging cat’s real name is Tardar Sauce but she prefers to go by Grumpy Cat.

Grumpy Cat has become so popular that she makes special appearances all over the country.

Grumpy Cat even has her own Facebook page with over 5 million likes and a Twitter page with over 200,000 followers.

She recently appeared on American Idol where she entertained the contestants, audience and even the judges.

Each judge decided to take a photo with Grumpy Cat and even tried to make their best grumpy face to match her signature expression.

Grumpy Cat even took the time to tweet about her American Idol appearance. Of course, she wasn’t the least bit impressed by the judges or any of the contestants, but she was willing to share a few photos.

Although Grumpy Cat has a bad attitude, her life is pretty great and she makes more money than most humans. As of March of last year, Grumpy Cat was worth over $1 million. As she continues to become more popular and receive more endorsements, her net worth will grow.

Grumpy Cat could become the richest animal on the planet and that is nothing to frown about.

What do you think of Grumpy Cat and her appearance on American Idol?
