John Stamos Got A Nick Jonas Tattoo?

This Instagram prank war between John Stamos and Nick Jonas is getting a little out of hand! It all started when Stamos wore a Jonas Brothers t-shirt to the American Music Awards. Then Nick wore a shirt with John's pic on it. It keeps on going with pillows and blankets, but John has taken it to the next level with a tattoo of Nick's face?

We are pretty sure it's fake, but who really knows?
