Lindsay Lohan's violent romance

Feb 8, 2010, 16:39 GMT

Lindsay Lohan was allegedly beaten up by on/off girlfriend Samantha Ronson.

The 'Mean Girls' actress - who has a turbulent relationship with the DJ - reportedly told a pal how the romance had, at times, been very violent, with Lindsay having the scars to prove it.

The friend said: "One time I saw Lindsay and she had a large welt on her head. She told me that Sam beat the s**t out of her.

"She also said that Sam even punched and choked her one time."

Although they have officially broken up, the two women still have regular contact with each other, which makes things hard on Lindsay.

The friend added to Radar Online: "It's so twisted. They're not together, but they are. I never thought I'd ever say this, but I really do feel sorry for Lindsay. She is just lost. She's alone. She has no friends to turn to."

This is not the first time Lindsay has made accusations about Samantha.

Last month, she took to her twitter page to berate the DJ, accusing her of cavorting with two girls.

Lindsay, 23, wrote "caught" to Samantha before claiming: "Funny how I'm rushing back to see Samantha Ronson when she says she's with her step- bro alone - and 2girls? That wasn't mentioned. (sic)"

Although Lindsay was sending direct messages to 32-year-old Samantha - the sister of producer Mark Ronson - she did not reply to her.
