Cara Delevingne is the latest star to come forward and detail how she was almost sexually assaulted by Weinstein.
She says Weinstein tried to force himself on her and engage in a threesome with another woman at NYC hotel.
In a lengthy statement posted on Instagram, the British model-turned-actress said that after meeting Weinstein at a hotel restaurant he asked her to come to his room, where another woman was waiting for them.
Then, when she announced that she had to leave, Weinstein tried to kiss her on the lips as she prepared to walk out the door.
Delevingne, 25, said that she still got the part in the film, and has felt guilty about it ever since.
The actress has filmed two movies for the Weinstein Company, including her breakout role in the 2015 picture Paper Towns and the recently released Tulip Fever.
Harvey Weinstein says he "encouraged" his British wife to leave him and admits the sexual harassment scandal engulfing him has torn apart their marriage.
Fashion designer Georgina Chapman revealed last night she needs time away from her husband after a string of allegations of sexual harassment and assault.
Through a spokesman, Weinstein issued a new statement addressing the breakdown of his 10-year marriage, the Sun reports.
"I support her decision, I am in counselling and perhaps, when I am better, we can rebuild," the Mail Online reported.
"Over the past 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.
"I understand, I love her and I love our children and hopefully, when I am better, I will be in their lives again."
Chapman, 41, announced their separation last night, saying: "My heart breaks for all the women who have suffered tremendous pain because of these unforgivable actions. "I have chosen to leave my husband. Caring for my young children is my first priority and I ask the media for privacy at this time." It came hours after superstars Angelina Jolie and Gwyneth Paltrow claimed Weinstein targeted them early in their careers and he faced bombshell claims he raped three women including Italian actress Asia Argento.
His spokesman said he "unequivocally denies" any allegations of non-consensual sex.
Pulp Fiction producer Weinstein, 65, was also rocked by an NYPD tape recording in which he apparently admits groping a model's breast in 2015. Chapman was said to have been "furious and humiliated" by Ambra Battilana's allegation two years ago, which did not lead to a prosecution.
Just days ago Weinstein said his wife stood "100 per cent behind" him.
Former Head and Shoulders ad model Chapman, 41, is the co-founder of fashion label Marchesa.
She married Weinstein in 2007 and has two children with the movie mogul, who was one of Hollywood's most powerful figures until his fall from grace. At the same time as Chapman made the announcement that she was leaving her husband, Weinstein flew to Europe by private jet, where he will submit himself to a live-in facility, Tmz reports.
Chapman and Weinstein met in 2003, married in 2007 and are parents to daughter India Pearl, 7, and son Dashiell, 4. She is Weinstein's second wife.
Weinstein's wife's career may be doomed
Marchesa may also suffer as a result of its association with now toxic Weinstein.
The Hollywood Reporter quoted a New York fashion publicist as saying: "No star is ever going to want to wear the brand again."
Over the years it is believed to have benefited from Weinstein's ability to attract A-list supporters and his friendship with Vogue editor Anna Wintour.
A fashion publicist said: "He was the mastermind behind Marchesa - orchestrating deals and using his influence in terms of the celebrity connections for her on behalf of the brand."
The source added that "they both benefited from the relationship, but she certainly knew about his bad behaviour".
She also appeared in several Weinstein-backed films, including Derailed and The Nanny Diaries.
'You have done terrible things to women
It comes as an email from DreamWorks founder Jeffrey Katzenberg to Weinstein was made public by the Hollywood Reporter.
In the letter, Katzenberg describes himself as a friend of Weinstein's for "more than 30 years" but says he could not support the producer's bid to save his job.
As a last-ditch effort to save his skin, Weinstein wrote a "desperate" email to Hollywood's heavy hitters begging for them to help him save his job.
"As someone who has been a friend of yours for 30 years, I'm available to give you advice on how to at least try to make amends, if possible address those that you've wronged, and just possibly find a path to heal and redeem yourself," he wrote. "Having watched your reactions, seen the actions you have taken and read your statement, I will tell you, in my opinion, you have gone about this all wrong and you are continuing to make a horrible set of circumstances even worse.
"Here is the bottom line," Katzenberg wrote. "You stated in your email below that 'A lot of the allegations are false as you know'. Well actually I don't 'know' and giving the timing of the circumstances, I have no way of knowing.
"You have done terrible things to a number of women over a period of years," he continued. "I cannot in any way say this is OK with me. It's not at all, and I am sickened by it, angry with you and incredibly disappointed in you. I doubt this is what you want to hear from me and most likely you aren't interested in my advice but this is the way I see it."
UK takes hardline with Weinstein
UK Prime Minister Theresa May has praised women who had the "courage" to report allegations of sexual harassment by Weinstein, raising the prospect he could be stripped of his honorary CBE.
"Unwanted sexual activity" is unacceptable, she said, and called for all the allegations against the movie mogul to be fully investigated.
Weinstein was awarded the CBE in 2004 for his contribution to the UK film industry.
Meanwhile, Bafta has suspended Weinstein's membership after the sexual harassment allegations made against him by a string of women.
A statement on the official Bafta website today reads: "In light of recent very serious allegations, Bafta has informed Harvey Weinstein that his membership has been suspended, effective immediately.
"While Bafta has previously been a beneficiary of Mr Weinstein's support for its charitable work, it considers the reported alleged behaviour completely unacceptable and incompatible with Bafta's values.
"This has led to Mr Weinstein's suspension, and it will be followed by a formal process as laid out in Bafta's constitution.
"We hope this announcement sends a clear message that such behaviour has absolutely no place in our industry.
"Bafta will continue to work with the film, games and television industries to improve access to rewarding and fulfilling careers in safe, professional working environments."
