Lohan And Sam: It's Over!

Lindsay Lohan and Samantha Ronson have broken up after a crazed and crazy few days in Miami, RadarOnline.com has learned. No word yet on whether Lindsay will switch teams again, but we do know that she was in a Los Angeles-area bar the other night, telling everyone who would listen that she was single again. And yes, she was hitting on both men and women. The New York Post reported during the weekend that La Lohan and her DJ girlfriend got into a fistfight in Miami. That report has been denied, but people close to the duo tell RadarOnline.com that it's true and that it's just one small example of how explosive their relationship was.
