Patrick Schwarzenegger was all smiles at Coachella Friday ... Miley Cyrus was kinda smiling too, but it seems they were in a different zip code.
Patrick was front and center at the H&M party, mugging with a random dude, while Miley was in a studio with producer Mike Will.
Seems a little strange. Coachella is the place we expected to see the 2 of them together.
We've gotten them together 2 times since Patrick's epic Spring break trip to Cabo and they seemed tight enough.
