The singer took to the stage at the festival in Indio, California, last night wearing this matching black crop-top and shorts combo - and of course she totally rocked it!!
The cut-out body-con ensemble was combined with a pair of biker boots and an oversized gold choker necklace.
And of course she was running and jumping around the stage, giving the crowd the energetic performances we've come to love her for.
After giving everything she had during her performance, Ellie then jumped into the crowd to enjoy some other sets and shared the evidence on Instagram - and we don't bloomin' blame her. If we were performing at Coachella (we wish), then we would do exactly the same thing!
This year's Coachella line-up is pretty amazing with Outkast, Muse and Arcade Fire headlining the main Coachella Stage. And of course, as with all big music festivals, celebs flocked to join the crowd and party with the likes of Kelly Brooke, Cara and Poppy Delevingne, Kylie and Kendall Jenner all making an appearance.
