It seems Bethenny Frankel has a bone to pick with Kylie Jenner. On Wednesday, the 23-year-old makeup mogul took to Instagram to share a brief video of her 2-year-old daughter Stormi jumping excitedly while chanting, "first day of school!" In the video, followers got a brief glimpse of young Stormi's powder pink backpack, which Page Six reports is a Hermès Kelly Ado and sells for around $12,000.
