Shoe designer Paris Hilton predicts that BFF Nicole Richie will struggle to cope with her upcoming four day stint in the Los Angeles County Jai.

Nicole was sentenced to a 4-day stay in prison on Friday, after she pleaded guilty to driving under the influence of drugs. She must report to jail before September 28 and has also been instructed to pay a $2,048 fine and complete a twenty-oneday alcohol education course.

Paris has written a blog entry about how difficult it will be for Nicole:

“The prison sentence will be a real killer for her,” P.H explained. “I found my 45-day sentence so difficult. But I think Nicole will find it impossible.”
