Socialite Paris Hilton is coping "very well under the circumstances" after spending her first day in jail for violating her probation following a 2006 drunk-driving arrest. The 26-year-old began her 23-day jail term on Sunday night at 10:30pm. Her lawyer Richard Hutton yesterday told reporters gathered outside the Los Angeles jail where Hilton is incarcerated that his client is being held in a 100 square foot "administrative segregation" cell because she is a celebrity. Hilton is allowed outside of her cell for one hour each day "to be in the module, take a shower and talk on the phone." Hutton also confirmed it was Hilton's decision to enter jail under cover of darkness, in an attempt to avoid a "media circus."
