John Stamos Shares Hilarious Video Of 'Un-Casual' Bromance With Nick Jonas

There is nothing casual about Nick Jonas turning 32, at least not if John Stamos has anything to say about it!

The Full House alum took to Instagram on Monday (September 16) to wish longtime bromance bud Nick Jonas a happy birthday, shining a bright spotlight on their not-so-subtle admiration throughout the years.

The hilarious video opens with a photo of the duo, preparing the audience to view "causal things Nick and I did at the start of our bromance," set to Chappell Roan 's, "Casual" of course. The birthday tribute proceeds with photos of both Stamos and Jonas wearing paparazzi photos of each other on their shirts, pillows, and bed clothing, concluding with Stamos getting a tattoo of Jonas' face on his forearm.

As the slides proceed, Stamos reveals that there is nothing casual about his bromance with the "Jealous" heartthrob. In fact, their entire relationship is "very un-casual actually...like super un-casual".

Fans sounded off in the comment section showering the A-list camaraderie with support stating, "We as a society moved on from this saga too quickly," and "I fear this is too iconic ..."

Stamos and Jonas' beloved bromance began in 2018 when Stamos wore a Jonas Brothers t-shirt at the American Music Awards, according to GQ Australia . The pair continued to wear clothes with each other's faces on them as their friendship blossomed, and the rest is history!
