"Heartbreaking…. wouldn't be surprised if this happened to my good friend @Jason_Priestley who punched Weinstein in the face at a club one night. Go Jay," she wrote.
That's when the Beverly Hills 90210 actor confirmed the story, describing what had happened on Twitter.
"Of course there is more to the story… '95 Golden Globes… at the Miramax Party… Harvey told me I had to leave… I was leaving when he grabbed me by the arm and said 'what are you doing?' I said 'you told me leave, I'm leaving'," Priestley recalled.
"'I didn't say you had to leave' he replied. 'You just told me to leave... right over there' I tell him once again. Getting heated now. He then grabs me tighter and says 'why don't we go outside and talk about this'. That was all I needed to hear."
'"I'm not going anywhere with you" I said as I pushed him back and punched him with a right hand to his face. Suddenly, there were security guards pulling us apart and I was escorted out of the party... "
On Thursday, Jackson told Stuff how Weinstein vetoed Judd and Sorvino from his Lord of the Rings Trilogy in the late 1990s.
The director was eager for them to be involved in the Miramax production but said that Weinstein put a stop to it.
'I recall Miramax telling us they were a nightmare to work with and we should avoid them at all costs. This was probably in 1998.
'At the time, we had no reason to question what these guys were telling us - but in hindsight, I realise that this was very likely the Miramax smear campaign in full swing.
'I now suspect we were fed false information about both of these talented women - and as a direct result their names were removed from our casting list.'
Judd was among the first women to speak out against the 65-year-old in an explosive New York Times article in October.
In response to Thursday's article, Mira tweeted: 'Just seeing this after I awoke, I burst out crying. There it is, confirmation that Harvey Weinstein derailed my career, something I suspected but was unsure. Thank you Peter Jackson for being honest. I'm just heartsick.'
