There is an ongoing joke between the judges on American Idol because Luke Bryan will not take his vitamins by mouth.

Katy Perry keeps up with all the Hollywood trends and makes sure to drink her ‘green juice’ that’s filled with vitamins and nutrients.

Katy tried to get Luke to drink some, but he wouldn’t budge explaining that he doesn’t need any of that.

So Katy Perry took matters into her own hands to make sure Luke was getting the vitamins he needed.

During the American Idol auditions, Luke walks on set to find an IV bag by his chair.

So Luke gets an IV placed into his arm to get some vitamins in his body.

Of course the contestants walk in very confused as to what is going on…
