The Keeping Up With The Kardashians star was pictured looking super glamorous on Tuesday (12 January) as she and make-up artist Joyce Bonnelli arrived for their flight at Los Angeles International Airport.
But a few hours later she tweeted: "Supposed to be in NYC but somehow I'm in Vegas. NYC I'm trying to get there. Emergency landing but Joyce and I are SAFE."
Khloe, 31, kept herself occupied at the airport by sipping on cocktails.
She's currently on the promo tour for her brand new TV show Kocktails with Khloe. The format sees Khloe inviting people round to her house (well, a set designed to look like her house) for dinner, cocktails and plenty of gossip. Cameras are hidden all over the place to catch their candid chat.
Khloe told Cosmopolitan last week: "I'm not a traditional talk show host. I don't want to be interviewing [people] on some couch. I don't think that's authentic."
