Three of the women say he pushed for sex as a condition for representing them and that he did not take them on when they refused.
A fourth said he offered to help advance her career if she agreed to have sex with him monthly.
Midway through her performance, she said Cirrincione grabbed her and started kissing her, sticking his tongue in her mouth.
She said he told her he could take her on as a client, on the condition that he would get to see her for sex whenever he wanted. Lamison is among nine women -- eight African-Americans and one Asian-American -- who have told The Washington Post that Cirrincione made unwanted sexual advances toward them over a period of two decades.
Two women said they later heard about other actresses' experiences with Cirrincione, one from her manager and the other from her attorney.
The women interviewed by The Post said they stayed silent for years about the harassment they said they endured because they feared repercussions to their careers and reputations.
She said he told her he could change her life if he signed her -- just as he had for Berry and Henson.
Another actress who met Cirrincione in 2005 during the Los Angeles premiere party of "Hustle & Flow," featuring Henson, said the manager invited her to audition for him.
She was 36 at the time, with no television or film credits.
Soon after her arrival at the hotel, Cirrincione's phone rang. He put the famous actress on speaker as Lamison listened in silently, in awe -- thinking that perhaps Cirrincione could steer her own acting career to Hollywood success in an industry with few leading roles for African-American actresses like herself.
When the call ended, Lamison began reciting a poem she had written.
He told her to think about his offer, she recalled.
