From dancing to Beyoncé's 'Single Ladies' at the US Tennis Open to 'bro-biking' through the Hamptons, it's safe to say presenter Jimmy Fallon and BFF Justin Timberlake have well-and-truly cemented their friendship in the celebrity Hall of Fame.

So, it came as no surprise the singer thought it apt to wish his best bud a 'happy birthday' with a Timberlake-Fallon-inspired Instagram post and caption to rival all birthday messages.

Last night, the father-of-one posted a picture of himself and Fallon chilling out by a BBQ drinking beer with the caption:

'Happy Birthday, @jimmyfallon. Remember that time when we were just two bros hanging out, drinking beer, grilling hamburgers and hot dogs and talking about life and who had the better hairline and who was always the first to crack up in our sketches...

'OOOH, and who would probably cry the most at the animated movies our kids watched and who was the nicer one of us two and crazy stuff like why do you park on a driveway and drive on a parkway?! Yeah... I remember that too!

'Just two bros. Hanging out. Doing bro stuff.'

Cute, right?

In ode to Justin and Jimmy's friendship, here are some of our favourite BFF moments:

That time they took a friendship test

That time they took the p*ss out of hashtags

That time they went to summer camp... in October
