Harris used the front-facing camera to capture himself dancing around the kitchen and lip syncing to West's most popular verse from ScHoolboy Q's "THat Part" track, in which he raps, "Wifey gonna kill me, she the female OJ. Y'all don't feel me, man this ain't OK."
And if that weren't enough shade, the 32-year-old music producer spent the night hanging out with West's wife, Kim Kardashian, at Jennifer Lopez's birthday bash, hosted by Benny Medina and Beau Smart, in Las Vegas. This all comes one week after Kardashian leaked a phone conversation between Swift and West over his controversial "Famous" lyrics via Snapchat. (The chat proved that West did call Swift for approval over his "I feel like me and Taylor might still have sex" line, an exchange the pop star previously denied.)
Harris, Kardashian and Lopez were joined by Khloe Kardashian's ex, rapper French Montana, who shared a snap of the foursome over Instagram.
Earlier in the night, the birthday girl performed a sold-out show at the Axis Theater at Planet Hollywood as part of her All I Have residency. In typical fashion, Kardashian took to Snapchat to share a few highlights, calling the "Ain't Yo Mama" singer a "queen."
Lopez's rep tells ET Iggy Azalea, LA Reid, John Stamos, and Cristiano Ronaldo were amongst the other celebrities sitting in the audience at the diva's Saturday night show.
