NEW YORK (AP) _ A woman who faces sentencing Friday for trying to extort $40 million from Bill Cosby has apologized in a letter sent to the judge, the Daily News reported today.

``Ms. (Autumn) Jackson now appreciates that she acted inappropriately in her dealings with Mr. Cosby, causing him great pain and embarrassment,'' according to the letter sent to federal Judge Barbara Jones.

``She also realizes, painfully, that she will never have any relationship with the famous man she has always believed to be her father,'' the letter written by Ms. Jackson's attorney Robert Baum continues. The newspaper did not say when the letter was dated.

Ms. Jackson was convicted in July of plotting to extort $40 million from Cosby by telling the tabloids she was his out-of-wedlock daughter.

Cosby admitted having an affair with Ms. Jackson's mother but said he does not believe the young woman is his daughter.

In their letter to the judge, prosecutors asked that Ms. Jackson be given a sentence ``sufficient to reflect the gravity and reprehensibility of (her) offense.''

Federal sentencing guidelines suggest a sentence of between 57 and 71 months in prison. The judge could reduce that penalty.
