According to Hollywood Life, the young ladies have been taking jabs at one another on social media, with fans noticing the subliminal back-and-forth.
It all apparently got started when Jenner, 19, took to Instagram on April 4 to share a photo of herself with the subtle caption, "kylie f*****g jenner."
Some saw it as shade to Snyder, 21, whose IG username is "@sarahf*****gsnyder." However, Jaden's ex seemed to have noticed the alleged shade, posting a selfie of her own with the caption, "One n only."
The IG feud took on a life of its own when a fan shared a photo of Kylie posing similarly to Sarah in a recent photo. Sarah, addressing Jenner directly, reposted the photo alongside hers on her Instagram story with the caption, "u channeling me sis?"
Though she deleted it soon after, a fan got a hold of a DM exchange where Sarah wrote, "Oh na deadass the same picture," showing she was bothered that the youngest Jenner was seemingly stealing her swag.
The bad blood between these two may lead to their mutual past involvement with Jaden Smith, as they both dated him at some point in time.
Oh, the life of the rich — privileged — and famous.
