Recently unsealed testimony from a 2005 case against Bill Cosby puts the famous faces who have stood up for the 77-year-old comedian in an uncomfortable position.

Stars Jill Scott and Whoopi Goldberg vehemently defended the accused rapist and former sitcom star, as did his “Cosby Show” costars Phylicia Rashad and Keshia Knight Pulliam, though they did so with less exuberance.  

The unsealed testimony revealed that the legendary funnyman admitted to purchasing quaaludes with the intent to give them to young women he hoped to have sex with.

Scott took to Twitter to admit she had been wrong.

“About Bill Cosby,” Scott wrote on Twitter late Monday, “sadly his own testimony offers PROOF of terrible deeds, which is ALL I have ever required to believe the accusations.”

She continued, “1) We live in America. Many African American men are detained &/or imprisoned for crimes without evidence. I will never jump on bandwagons. 2) Based on social media or hearsay. Proof will always matter more than public opinion. The sworn testimony is proof. Completely disgusted.”

Scott explained that she stood by Cosby because she “respected and loved” him. “I was wrong. It HURTS!!!... Reasoning with the angry & unreasonable? No. I'm not sorry for standing by my mentor. I'm sorry the accusations [are] true.”

The recent Cosby revelations came from comments he made in 2005 when he was being questioned by a lawyer for former Temple University employee Andrea Constand, who accused him of sexual assault. That was settled before trial.

Cosby also answered questions about a sexual relationship with a woman in 1978. The woman went public last November with allegations he drugged and assaulted her two years earlier, when she was 19. That woman has accused Cosby of defamation over his denials.

In reference to that incident, Cosby recalled, “I meet (the accuser) in Las Vegas. She meets me backstage. I give her quaaludes. We then have sex.”

The release of the new testimony was not enough to convince Goldberg or former co-star Raven Symoné of his guilt, they said on "The View" Tuesday. 

Goldberg cautioned viewers against making snap judgments against Cosby while Symoné didn't contribute much to the conversation except to say it was a tough topic for her to discuss as she credits the TV icon with helping her break into show business. 

These latest revelations have also served as more ammunition for some of Cosby’s most emphatic critics.

Judd Apatow, who has repeatedly criticized Cosby, tweeted, “It's a very sad situation. Now can we all stand up and support the victims? Will silence continue?”

The director took the opportunity to demand answers from some of Cosby’s famed defenders, “I also hope Camille Cosby and Phylicia Rashad will now stand with the victims and not with their attacker,” he told Esquire.

Reps for Goldberg, Rashad and Knight Pulliam did not immediately return FOX411’s request for comment regarding the latest Cosby news.
