British model and actress Cara Delevingne is the latest celebrity to claim she received unwanted advances from movie mogul Harvey Weinstein.
In a post on Instagram , she said she was invited up to his room where he asked her to kiss another woman, before later trying to kiss her on the lips.
It came as the Academy of Motion Picture Arts and Sciences, which hand out the Oscars, said they would be holding a meeting on Saturday to discuss any action to be taken.
Delevingne wrote on Instagram: "I went to a meeting with him in the lobby of a hotel with a director about an upcoming film.
"The director left the meeting and Harvey asked me to stay and chat with him. As soon as we were alone he began to brag about all the actresses he had slept with and how he had made their careers and spoke about other inappropriate things of a sexual nature.
"He then invited me to his room. I quickly declined and asked his assistant if my car was outside. She said it wasn't and wouldn't be for a bit and I should go to his room.
"At that moment I felt very powerless and scared but didn't want to act that way hoping that I was wrong about the situation.
"When I arrived I was relieved to find another woman in his room and thought immediately I was safe.
"He asked us to kiss and she began some sort of advances upon his direction. I swiftly got up and asked him if he knew that I could sing. And I began to sing....i thought it would make the situation better....more professional....like an audition....i was so nervous.
"After singing I said again that I had to leave. He walked me to the door and stood in front of it and tried to kiss me on the lips. I stopped him and managed to get out of the room."
She said she ended up being given the part in the film but later felt "awful" and "guilty" about whether she had done something wrong.
Delevingne does not state what the film was, but she played a part in the Weinstein Company film Tulip Fever - released last month.
Weinstein has been accused by a number of women of sexual harassment and rape in a case that threatens to wipe out the career of one of Hollywood's most powerful figures.
Gwyneth Paltrow and Angelina Jolie are among those who have accused the producer of unwanted advances.
Another actress who claimed he tried to kiss her was Bond girl Lea Seydoux, who appeared in Weinstein-funded Inglourious Basterds, and told The Guardian: "He suddenly jumped on me and tried to kiss me. I had to defend myself. He's big and fat, so I had to be forceful to resist him."
Weinstein continues to "unequivocally deny" allegations of non-consensual sex against him and of illegal sexual harassment.
The Academy of Motion Picture Arts and Sciences said the sexual abuse allegations against Harvey Weinstein were "repugnant" and "abhorrent".
He has won one Best Picture Oscar as producer for Shakespeare in Love and five as executive producer for The English Patient, Chicago, Lord of the Rings: The Return of the King, The King's Speech and The Artist, and has been nominated for 16 other Best Picture Oscars as either producer or executive producer.
But the films he backed have also won dozens of Oscars for their stars, directors and other crew members.
Earlier on Wednesday, Weinstein's was suspended from BAFTA .
The academy said it wanted to send a "clear message that such behaviour has absolutely no place in our industry".
A former aspiring actress also told Sky News she changed her career after being subjected to sexual harassment by Weinstein.

Tomi-Ann Roberts said she was attempting to land a role in an early Miramax film when Weinstein tried to force her to strip half naked.
She said she was left so shocked that she quit acting and became a doctor.
She told Sky News: "I was a 20-year-old college student spending the summer in New York City with friends, trying to pursue our dreams.
"I was waiting tables and happened to meet Harvey and Bob Weinstein. I was told they were going to write and direct their first movie, which led me to believe I might have a chance to get cast.
"Over the course of the summer I read several scripts then had a pretty disturbing encounter with Mr Weinstein himself.
"He was in a bathtub. He tried to coerce me to take my top off and I didn't and I ended up leaving that situation and actually leaving my acting aspirations."
Theresa May's spokesman also hinted that the Prime Minister supported taking away his CBE for services to the film industry.
He said: "The independent Honours Forfeiture Committee considers cases where the honours system has been brought into disrepute.
"Their discussions are confidential. It is right that we let them get on with their work."
The growing condemnation comes as The New Yorker said Asia Argento, an Italian actress, had told the magazine that Weinstein forcibly performed a sex act on her.
She and two other women allege that Weinstein raped them, The New Yorker said.
The magazine also published a recording of Italian model Ambra Gutierrez telling Weinstein she is "not comfortable" as he tells her repeatedly to come and sit next to him and to go to the bathroom to take a shower.
On Tuesday, Weinstein's wife also announced she was leaving him after his "unforgivable" behaviour.
In a statement, Weinstein said: "Over the last week, there has been a lot of pain for my family that I take responsibility for.
"I sat down with my wife Georgina, who I love more than anything, and we discussed what was best for our family.
"We discussed the possibility of a separation and I encouraged her to do what was in her heart. In the end, she made the decision to separate.
"I understand, I love her and I love our children and hopefully, when I am better, I will be in their lives again.
"I support her decision, I am in counselling and perhaps, when I am better, we can rebuild."
