Amped up! Kylie Jenner showed her sisterly support for model sibling Kendall Jenner as she walked the Alexander Wang fashion show on September 11 in NYC.

Despite the fact that most other attendees kept mum while the models strutted by in bralette crop tops, wide leg trousers and glittering skirts, the Kylie Cosmetics founder, 19, couldn't contain her enthusiasm. She hooted and hollered as her older sister passed her, screaming, "Wooo, Kenny!" and documented the entire thing via Snapchat.

Even with her sister's unexpected outbursts, Kendall, 20, kept it professional and didn't miss a step or crack a smile.

But Kylie has more than just familial pride to be psyched about at the Alexander Wang show. She announced that she's part of the #wangsquad campaign alongside on-again love Tyga, Zoe Kravitz, Big Sean and more on September 6. "@wangsquad coming soon #WANGF16,” the Keeping Up With the Kardashians star captioned a shot of herself in head-to-toe duds by the label, which was later re-'grammed by the Wang Squad account.

Another Wang Squad member, Skrillex, also took in the star-studded show, as did Madonna, her daughter Lourdes, Rami Malek, Nicki Minaj, Will.i.am and Fetty Wap.
