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.
The girls looked like they had a fantastic time and wore some pretty festival-appropriate hats.
FYI, Serafino plays Cosgrove's TV sister on her new show, Crowded.
Past or present,
Carly and SamMiranda and Jennette are forever.
