The flame-haired actress is reluctant to go into detail about the incident but suggested Egor's judgement was clouded by alcohol.
She told the Mail on Sunday newspaper: "Egor drank too much and he went crazy."
The duo had another fight on the balcony of the flat they shared in Knightsbridge, London, which was filmed by a neighbour.
During that incident, Lindsay accused Egor of assaulting her, shouting: "Please, please. He just strangled me. He almost killed me."
The police were subsequently called to the scene but no-one was charged.
Reflecting on the balcony incident, Lindsay said: "Egor and I had been out for dinner. We danced, it was fun.
"When we got home I went to bed and Egor went out. A few hours later he came back and when I woke up he was standing over me. He wasn't himself, he was being very aggressive and he attacked me."
The pair have not seen each other since, but Lindsay admits to feeling unsafe.
She explained: "I've kept quiet for so long but now I'm scared of what Egor might do to me and to himself'
"It's not the first time. That's the problem. But this time, someone saw. I didn't call anyone, I've dealt with enough police in LA. I just left the house and went to the Connaught [Hotel] for the night.
"I contacted my good friend [Israeli socialite] Hofit Golan who was in St Tropez. She said, 'Get on a plane, come and meet me,' so I did. I needed some time for myself.
"I've spent the past week fishing on my friend Marco Mavilla's yacht with his lovely family in Sardinia."
Despite this, Lindsay has contacted Egor in recent days and suggested the two could still reconcile their differences.
She shared: "I need closure. I genuinely fell in love with him but he broke my trust and made me feel unsafe.
"I know I'm not an angel but I've tried to fix things. It's down to him now. I had suggested we go for couples' counselling but there comes a time when I have to put myself first, my family, and also think about my career which I've worked so hard for. I also don't want to let my fans down by not being the strong woman I have become."
