Tons of important events went down at Coachella's kickoff weekend, from Kesha's surprise performance during Zedd's set, to Rihanna and Calvin Harris performing "We Found Love." Another memorable celeb duet occurred that didn't involve any singing — but plenty of nostalgia.

Miranda Cosgrove and Jennette McCurdy, stars of Dan Schneider's show iCarly, partied it up at the Cali music festival because Carly and Sam are forever besties. Cue the "random dancing" sound effect.

The girls looked like they had a fantastic time and wore some pretty festival-appropriate hats.

Besides each other, Cosgrove and McCurdy hung out with pals Mia Serafino and Sarah Ortiz.

FYI, Serafino plays Cosgrove's TV sister on her new show, Crowded.

Past or present, Carly and Sam Miranda and Jennette are forever.
