Next to photos of Stanley, Eilish wrote, “F**k. I don’t understand why is this all happening. I hate this. I don’t know how I’m only finding out now. You’re not here anymore. I love you so much Kira.”

According to Kira’s Instagram page, the 18-year-old was battling cancer and was diagnosed with Diffuse Intrinsic Pontine Glioma which is an aggressive brain tumour. Skylar, on the other hand, “collapsed, her heart stopped beating and she never regained consciousness” according to a GoFundMe page set up to help with her funeral expenses.

This unfortunate news comes just before Eilish kicks off her “Where Do We Go? world tour in March.
