Kourtney Kardashian suffered a claustrophobia attack as she arrived at Los Angeles International Airport.
The reality TV star - who is currently pregnant with her second child - started to get anxious while she was going through customs at LAX and had to take deep breaths to calm her down.
She tweeted: "Wow claustrophobia attack in customs at the airport. Not fun. Ahhhhh deep breath! (sic)"
However, Kourtney - who has two-year-old son Mason with her partner Scott Disick - soon recovered and celebrated her 33rd birthday yesterday (18.04.12) with a takeaway burger.
She wrote: "Just had IN N OUT for the first time! Can u believe it?! I asked @ScottDisick to get it for me tonight for a relaxing birthday din din. Yum. (sic)"
She also thanked everyone for their well wishes on her special day, saying: "Thank you all so much for the birthday wishes! Love u all so much! (sic)"
Kourtney has been suffering from claustrophobia since falling pregnant and recently took to her twitter page to ask for advice.
She wrote: "Deep breath. Been struggling a little with claustrophobia ... any other preggos feel that way too? (sic)"
