Nick Jonas and John Stamos are in a massive battle
...over who is the bigger fan of the other.
It all started when John Stamos, star of Fuller House, wore a Jonas Brothers T-shirt on the red carpet.
Nick Jonas then came out wearing a jersey with Stamos screen-printed on the front.
It escalated when John got that same image printed on a pillow,
Then Nick took it to the next level,
And now this, John has uploaded a photo of himself getting a tat of Nick's face on his forearm.
It's likely this is fake but if that's the case then there's probably only one way for Nick to top it...
