Nicole Richie seems to court controversy. The reality star is in the press again over an insensitive party invitation she e-mailed to friends last week.

The email, obtained by In Touch Weekly, reads, “My fellow Americans its that time of year
To celebrate our country by drinking massive amounts of beer
Let's stand together as one, live the American dream
Take shots, pass out, & wake up with our pants ripped open at the seems
Let's glorify this day in your sluttiest tops and your tightest pair of tsubi jeans
Even though we have no fucking clue what Memorial Day really means!!...
There will be a scale at the front door. No girls over 100 pounds allowed in. Start starving yourself now.�

The party, which took place on Sunday afternoon, certainly lived up to the invite. Mischa Barton was hospitalized after mixing alcohol with antibiotics for bronchitis, reported TMZ.com. Sources for Perez Hilton, however, claim Mischa had mixed psychedelic mushrooms with cocaine. Nicole was also doing her best to keep her weight under the invitation’s 100 pound minimum. "Nicole didn't eat anything" at the party, said one source.

A rep for Richie said that the invitation was meant to be a joke, but the starlet’s dwindling health is certainly no laughing matter. The reason for Nicole’s recent weight loss is stress. She is scared to death of winding up like her pal Paris Hilton, who is scheduled to begin a jail sentence next month. Says one insider, "When Nicole heard about Paris' sentence, she broke down. She's been eating less. She's only sleeping three hours a night. She has nightmares about being in prison and wakes up in cold sweats."

Dr. Majid Ali, a nutritionist, told In Touch, "I would place Nicole's weight at about 83 pounds. At 5'1", she should weigh 105 to 110 pounds. You can see a bit of bloat of her belly, consistent with a malnutrition syndrome. I would be very concerned for her health if I was a family member."
