Jennifer Lopez & Keith Urban Welcome Grumpy Cat to 'Idol'!

Keith Urban, Jennifer Lopez and Ryan Seacrest with Grumpy Cat on American Idol

The judges of American Idol welcomed a very special guest to the show on Wednesday night. 

Internet celebrity Grumpy Cat joined judges Jennifer LopezKeith Urban and Harry Connick Jr., as well as host Ryan Seacrest for a taping of the show on Wednesday in West Hollywood, Calif. The kitty cuddled up to the judges and contestants, and presumably helped J.Lo with her nuanced critiques.

But, how did Grumpy Cat feel about the performances? Well, she kept her poker face on, but it seems like she enjoyed the singing. The final six contestants impressed the judges (and the cat!) with two performances each, a rock song and a country song. Unfortunately, one singer will be booted from the competition during tonight's show. Who are you rooting for?
