The list of women accusing comedian Bill Cosby of sexual assault is still growing.

Three more women made their accusations public on Wednesday in a press conference held in their attorney Gloria Allred's office -- former flight attendant Colleen Hughes, as well as actresses Eden Tirl and Linda Ridgeway. The women join the reported 46 women who allege that the 78-year-old comedian had sexually assaulted them in the past.

According to Hughes, she met Cosby on a flight to Los Angeles in the '70s when she was a stewardess. She claimed she shared a glass of champagne with him back at his hotel room, and that they watched the news together, which was the last thing she remembers. Hughes said she woke up hours later, with her clothes all over the hotel floor, and felt semen on the small of her back.

For her part, Tirl said she was sexually harassed after meeting Cosby at a taping of The Cosby Show in 1989, when she was cast to play a cop in one of the episodes.

Ridgeway, who had a role in the 1972 film The Mechanic, said that unlike some of Cosby's accusers, she was not drugged. Telling her story in graphic detail, she said Cosby assaulted her in a director's office, when he "shoved [his penis] into [her] mouth."

Cosby has never been charged with a crime and maintains his innocence, and his legal team has yet to respond to the latest accusations. But in a 2005 deposition from a civil sexual assault lawsuit, which was made public last month, Cosby admitted under oath to obtaining Quaaludes to give to "young women" that he "wanted to have sex with."

Late last month, 35 of Cosby's accusers united to tell their story to New York Magazine. The magazine photographed and interviewed each woman separately, and noted that each of "their stories have remarkable similarities." Watch the video below for more on the powerful cover story.
