Who's the biggest Jonas Brothers fan? Well, turns out it's John Stamos and he's also a Nick girl. Aww!

The Jonas Brothers are at an all-time high right now after the release of their latest single 'Sucker' and so is the bromance between Nick and John Stamos.

The 'Full House' actor has never shied away from showing the JoBros some love and has worn a vintage Jonas Brothers t-shirt on more than one occasion.

A Jonas Brothers t-shirt at an awards show? Now that's true love!

This was a few months ago, but then this month, Nick decided to start a hilarious online war with John by posting this.

Good one, Nick. This is like 'Inception' but with custom t-shirts.

But then, for the next move, John had to think out of the box. He honestly won this round when he posted this last week.

Just look at him, sleeping so blissfully next to Nick. The bromance is getting intense now.

It was Nick's turn now and he made everyone wait for five days for his move but it was honestly worth it. Our national jiju really knocked it out of the park when he posted this.

Just imagine Priyanka Chopra and Nick Jonas going to sleep with a blanket that has a picture of John Stamos sleeping on a pillow with a picture of Nick wearing a t-shirt that has a picture of John wearing a Jonas Brothers t-shirt. Okay, now my head hurts.

This entire thing is like the Justin Timberlake and Jimmy Fallon coffee mug saga, but just on the next level.
