Sabrina Carpenter brought Geena Davis and Terry Crews to Coachella ... but, the biggest collab of the day might've been Fakemink with former First Son Hunter Biden!

The England native grabbed a pic with President Joe Biden's second child ... while holding what appears to be a joint in his left hand.

Fakemink threw up a peace sign while Biden slung his right arm over the rapper's shoulder and flashed a toothy grin for the camera.

Biden didn't jump onstage with the star ... a missed opoortunity, we gotta say.

It was all good vibes in the pic ... unlike the recent video Hunter posted challenging Donald Trump Jr. and Eric Trump to a cage match.

Coachella brings out the biggest stars in the world every year ... and, this time around was no exception.

Kylie and Kendall Jenner, Hailey Bieber, Will Ferrell, Susan Sarandon, Anya Taylor-Joy, Taye Diggs and a whole lot more made the trek out to Coachella Valley for the show.

It seems even former members of the First Family aren't immune to the festival's charms!
