The reality star kept her head down as she walked through the terminal following a week that saw her hitting the headlines for criticising brother Rob's ex-girlfriend Adrienne Bailon.
Kim, 33, voiced her annoyance after reading Adrienne's interview with Latina magazine in which Adrienne suggested being associated with the Kardashan name had been "hurtful" to her career.
Unhappy, Kim took to Twitter to say: "Funny how she says being with a Kardashian hurt her career yet the only reason she has this article is bc she is talking about a Kardashian."
Cheetah Girls star Adrienne, however, has now responded in a lengthy Instagram message which appears to be directed towards Kim.
"Fame and a career are two different things. I've always had a career. I have been working hard since I was 15 years old. Being someone's "girlfriend" was never what I wanted to be famous for," wrote Adrienne.
"What makes you "famous" isn't always what you want to be "labelled" as, or known for. If anyone should understand that… It should be you."
Many have taken that last part as a dig at Kim's infamous sex tape which helped propel her to stardom.
Adrienne continued: "I also stated in the article that none of this would have stopped me from being in love and being in that relationship. I just would have gone about it differently. You can love someone just as much in private. We all learn from our first loves."
Kim hasn't responded.
Yesterday, she was keeping her mind on more pleasant things, reminiscing about her recent holiday to Punta Mita, Mexico - and sharing a rare make-up free selfie. Yes, Kim Kardashian without make-up!
