Kylie Jenner and boyfriend Tyga landed at Los Angeles International Airport on Wednesday evening, and the duo were returning from New York City. Kyles was in the Big Apple to support big sis Kendall Jenner at the Victoria's Secret Fashion Show, and while we're sure she's proud of her sister, surely she has to be just a little bit jealous, right?

Earlier in the day Kylie tweeted, "Early morning in NYC. Too bad I felt under the weather during this trip :(." We know it's crazy, but our first thought was morning sickness, because let's face it -- would any of us be totally shocked if Kylie was preggers? She's been practically joined at the hip with Tyga since she turned 18 this summer, and since she's not walking the VS runway anytime soon, she's gotta do something to stay relevant!
