Since his time in prison, Cosby has received thousands of letters as well as thousands of dollars that have been placed on his books for use at the prison, Wyatt told WCAU.
Mr Wyatt added: "She has not visited him".
'He said the bed lies on thick steel or concrete and he's allowed to make phone calls, but he's still being assessed right now so he's not in general population, ' revealed Wyatt. "He does not want her to visit him".
His wife Camille has not visited him so far.
The disgraced comedian is now serving three to ten years in a Philadelphia maximum security prison after being convicted last year for drugging and sexually assaulting his friend Andrea Constand in 2004.
Cosby has also lost weight since being jailed and wakes at 3.30am each morning to exercise.
Bill Cosby is apparently having the time of his life in prison. "Now the amusing part about it (is) Mrs. Cosby's been trying to stop him from drinking coffee for 55 years and it took this to stop him from drinking coffee", Wyatt said. The sexual predator was known as "America's Dad" after starring as the family head in hit US TV series The Cosby Show.
After a stint in a single-cell unit, he was recently transferred to another unit, where he is able to interact with other inmates. "He does not eat in the area with other residents, he does not have a cellmate, and he does not exercise with other residents", Wyatt said.
Amy Worden, a press secretary for the Pennsylvania Department of Corrections, said the area in which Cosby is being held is centered around a "day room" where inmates can socialize, watch television and play cards.
Wyatt did not explain how Cosby did that however, since he was removed from the general population at that time.
