It was business as usual for Kim Kardashian
On June 12 she'd spent the day fending off tabloid rumors while boyfriend Kanye West
was in Switzerland for a performance at Art Basel, the last stop after several weeks of traveling before his album Yeezus
debuted June 18.
As for the scandal du jour, a report that West had cheated with a model, she wasn't letting it get to her. "Kim thought it was absurd and dismissed it," says a friend.
And as she sat down to lunch at Sherman Oaks, Calif., eatery Casa Vega with pal Jonathan Cheban and the Keeping Up with the Kardashians
cameras in tow, she seemed perfectly relaxed, "smiling," says an onlooker, "looking really happy."
Just two days later, however, calm turned to chaos as Kardashian, 32, was rushed to the hospital with complications to her pregnancy and suddenly found herself in labor roughly three weeks before her due date.
