The couple's tumultuous romance came to an end last year, but the famous pair hit the headlines again last week after they were rumored to have engaged in a public bust-up at a Hollywood night club.
Reports published on Radar Online suggested the couple's former relationship had been marred by incidents of domestic violence. But Lohan has finally denied the rumors, in a post on her Twitter.com page, she writes, "This is become a bit much. Samantha R never raised a hand to me, I've never said she did. Enough is Enough. Focus on other more important..."
Ronson quickly re-posted Lohan's message on her own Twitter.com page and added, "THANK you for clearing that up. The high road was giving me a nose bleed! To ANYONE who perpetuates this rumor accusing me of being violently abusive after Lindsay Lohan has denied it: I WILL take legal action. Sorry to sound so stern - but that sort of s**t is not cool."
