If this isn't giving us all the 4th grade BFF feels...
We knew Jimmy Fallon and Justin Timberlake were close, but on Monday, we found out just how much the two actually mean to each other.
Fallon was on Watch What Happens Live with Andy Cohen when a fan asked about the most "bromantic" thing he and Timberlake had ever done for each other.
The Tonight Show host expressed he had "never talked about this," but revealed:
"For his 40th [birthday], I gave him half of a medallion that says 'brothers forever.'"
Cue all the "awwwws" from Cohen and the fan.
He continued:
"So I have one half and he has one half."
When Cohen asked Fallon if he was sporting the hardware presently, Fallow quipped:
"Yes, but not around my neck."
You can watch Fallon spill below.
Many viewers of the segment made a crack about the classic SNL Lonely Island Boys song featuring Timberlake...

But the gift didn't come as a surprise to any of the viewers.
Fallon and Timberlake also adorably read "sweet tweets" to each other last year on Jimmy Kimmel Live which gave viewers all kinds of fuzzy feelings about their bromance.
