Minka Kelly Slams Jesse Williams Cheating Story & Harvey Weinstein On Instagram

She hasn't publicly confirmed that she's even dating him, but Minka Kelly has officially shut down rumors she and "Grey's Anatomy" actor Jesse Williams cheated, which led to his 13-year marriage coming to an end.

Kelly took to Instagram with a post showing off a new hairstyle, but things quickly became far less innocent seeming when a fan commented on it, asking her if the rumors she had cheated were true. The comment has since appeared to be deleted.

"I hope the cheating rumors aren't true. It would be disappointing," the commenter allegedly wrote (as per Us Weekly).

Minka quickly fired back, writing "They're not. Hate for you to be disappointed. Glad I could clear that up for you. Now **** off."

Fans quickly noticed the exchange, leading to more comments about it, with some praising the actress for standing up for herself.

"You roasted someone here but I think they removed their comment. 'Now **** off' hahah," one wrote.

"I don't know where your '**** off' comment when but it was pretty awesome," another fan added.

Those comments led to Kelly responding for a second time, saying she stood by it because she wasn't going to let anyone make false assumptions about her life.

" I didn't delete it and I stand by it," she wrote. "Anyone and their assumptions about my personal life can do the same."

Us Weekly previously broke the story that Kelly and Williams had begun dating earlier this year, and that Williams and his estranged wife, Aryn Drake-Lee, filed for divorce in April. The pair have been battling over custody arrangements for their two children, Sadie,3, and Maceo, 2, ever since.

Prior to Kelly's Instagram comments, the only acknowledgement from the rumored pair about their romance came from Williams appearing in Jay-Z's "Footnotes for 4:44" video, where he addressed his divorce and also trashed rumors that he had cheated on his wife, without naming Kelly or confirming he was dating her.

"I was in a relationship 13 years, 13 real years, not five years, not seven years, 13 years," he said. "And all of a sudden mother f***ers are writing think-pieces that I somehow threw a 13-year relationship—like the most painful experience I've had in my life, like with a person I've loved with all of my heart—that I threw a person and my family in the trash because a girl I work with is cute."

Kelly has since moved on from the controversy to share a different post to her page, where she shared a photo of a cross-stitch pattern, and addressed the Harvey Weinstein scandal, adding her name to the growing list of women who have claimed they were harassed or worse by the disgraced movie mogul.

"I met Harvey at an industry party. The following day, my agent said he wanted to see me for a general meeting. The location was set for his hotel room. I wasn't comfortable with going to his room & said so. The following day, we sat down with an assistant in the hotel restaurant. He bull**** me for 5 minutes re: movies he could put me in, then asked the assistant to excuse us. As she walked away, he said, 'I know you were feeling what I was feeling when we met the other night' and then regaled me with offers of a lavish life filled with trips around the world on private planes etc. IF I would be his girlfriend. Or, 'We could just keep this professional,'" She recounted. "All I knew was not to offend this very powerful man and to get out of the situation as quickly as possible. I told him while flattered, I'd like to keep things professional. He said, 'Fine, I trust you won't tell anyone about this.' I said 'Of course not. Thank you so much for taking the time to meet with me,' -- the only way I could think to shut it down gracefully and excuse myself."

Kelly went on to say she regretted letting him get away with the incident and applauding the other women who have since come forward with their stories, calling for change in Hollywood so no other woman had to deal with such a similar situation again.

Among the other women who have since spoken out and accused Weinstein of a variety of crimes are Ashley Judd, Rose McGowan, Angelina Jolie, Gwyneth Paltrow, Cara Delevingne and Kate Beckinsale. Scores of other actors and actresses have also since condemned his actions.
