Samantha Ronson has dumped on-again and off-again lover Lindsay Lohan for one more time. E! News which exclusively reports the story claims the lesbian lovers called it quits on Monday, June 15 after involving in a heated argument over the DJ's friendship with reality TV star Nicole Richie, who apparently doesn't like Lindsay.
The argument actually broke off last week when Nicole invited Sam to attend the birthday party of a mutual friend held at Bar Marmont with one condition, that was she didn't bring Lindsay to the bash. "Sam went to the party, and it really upset Lindsay," says a source.
Things got worse when Sam had dinner with Nicole at Izakaya on Monday. Another source claims it was after the dinner that Sam dumped Lindsay. Both Sam and Lindsay remain silent on the separation report. Meanwhile, representative for Sam declines to comment on her personal life, whereas representative for Nicole cannot be reached for comment just yet, E! News reports.
