Bill Cosby, 81, has just been sentenced to anywhere from three to ten years in prison for his sexual assault conviction, after prosecutors and defense attorneys agreed to merge the three counts of his conviction into one for sentencing purposes. Cosby will begin serving his sentence immediately at a Pennslyvania state prison.

"This was a serious crime. Mr. Cosby this has all circled back to you. The day has come, the time has come," Judge Steven O'Neill told him in court.

In April, Cosby was found guilty of three counts of sexual assault for drugging and molesting Andrea Constand in 2004. Constand delivered her full victim impact statement this morning, and the judge ruled that the TV star must register as a "sexually violent offender," despite his defense's insistence that he was not a threat due to his age and partial blindness.

He will need to register with state police and notify any community he lives in of his sex offender status, as well as undergo mandatory counseling for life.

"When the sexual assault happened, I was a young woman brimming with confidence and looking forward to a future bright with possibilities. Now, almost 15 years later, I'm a middle-aged woman who's been stuck in a holding pattern for most of her adult life, unable to heal fully or to move forward," Constand said in her statement.

"I had to relive every moment of the sexual assault in horrifying detail in front of Mr. Cosby and his lawyers. I felt traumatized all over again and was often in tears. I had to watch Cosby make jokes and attempt to degrade and diminish me, while his lawyers belittled and sneered at me," she explained in another part.

"We may never know the full extent of his double life as a sexual predator but his decades-long reign of terror as a serial rapist is over," she added.

Justice has been served.
