Nicole Richie, Mischa Barton and her sister Hania, picked up a few things from the grocery store for their Memorial Day BBQ. The party took a turn for the worse when Mischa had to be rushed to the hospital! Supposedly she was recovering from bronchitis for the past few weeks and didn't know you're not supposed to mix alcohol with antibiotics. Now, however she is said to be "resting comfortably" and "feeling much better." When you've got bronchitis it means you need to rest. Obviously she learned that lesson the hard way! As for Nicole, she seems to be following in Britney's barefoot footstep trend. Gross.
