Los Angeles ? Paris Hilton said Saturday she was “learning and growing” from her time behind bars and will not appeal her 45-day jail sentence for a probation violation in a reckless driving case.

The hotel heiress was at a maximum-security detention center, where she was believed to have undergone medical and psychiatric evaluations to determine the best jail to keep her in.

“Being in jail is by far the hardest thing I have ever done,” Hilton said in a statement released by her lawyer, Richard A. Hutton. “During the past several days, I have had a lot of time to think and I believe that I am learning and growing from this experience.”
