We think she forgets her dad is Caitlyn!

Kylie Jenner grabbed lunch at Le Pain Quotidian in Calabasas this afternoon, and the reality star was rocking one of Kanye's Yeezy season 3 t-shirts featuring the late Robert Kardashian and Donda West. Are we the only ones that find this slightly weird? She's definitely Kris Jenner's daughter, because she was also rocking Puma sneakers to fulfill her end of her endorsement deal with the brand.

With the launch of her clothing line and the success of her lip kit, Kyls is proving to be a force to be reckoned with in the famous family, but Kim insists she's totally fine with sharing her crown. "Kylie and I laugh so hard at this all the time, because people always want to pit us against each other, thinking we have similar careers. I think it's amazing – there's no one else I would want to be in the same business with than my sister. She teaches me so much, and I teach her so much, and we're both so close that it's just funny," the mother-of-two wrote on her app.

If the 18-year-old wants to be on the same level as Kimmy K, she needs to learn how to behave like her. Last night, Tyga's lady love lashed out at a young fan asking to take a photo with her, and it wasn't a good look! This morning she took to Twitter to try and clarify why she was such a little b**ch.

"She wasn't annoying. She came in the restaurant after and I had a talk with her and we took photos," she explained of the traumatized fan. "She just apologized for grabbing on to me so hard... & said she was a big fan and we embraced & took pics. I just said u can't be doing that. It's scary when I can't see & have no [security] already," she added.

It's Kylie's world and we're just livin' in it!
