The socialite was returning to Los Angeles from the Bahamas - where she had been taking part in a photoshoot with teenage singer Justin Bieber - and admits constant travelling is taking its toll. She tweeted: "All of this traveling with delays, weather changes, and early hours has gotten me sick...I hate this feeling. I need a break from planes. "After waiting a hour on the runway...they tell me my bags didn`t make it and are lost!!!! I want to cry :-( (sic)" The 29-year-old beauty`s evening failed to improve when she finally arrived back to her house - and was unable to get inside. She added: "Ok just when I thought my night couldn`t get any worse, I get home just craving my own bed and IM LOCKED OUT!!!!! (sic)" Despite her series of mishaps, Kim had earlier tweeted about how much fun she was having with 16-year-old Justin. She posted: "Bahamas with my Biebs! Fun shoot!"
