Swift and the group have been having a "great time," one onlooker told PEOPLE on Friday
Don’t call it a squad – call it “family.”
A second shot, of her, Antonoff and Lorde by the pool, was simply captioned with a celebratory emoji.

Swift and the group have been having a “great time,” one onlooker told PEOPLE on Friday. They were seen dancing and singing along to Borns’ performance that day, and also spent time in the VIP area. Swift will likely stay the entire weekend as her boyfriend, Calvin Harris, is headlining Sunday’s day of music.
Who would have guessed Swift was a Coachella newbie?
