Celebrity informants tattle that Lindsay Lohan was partying with gay girlpal Samantha Ronson before the pair got into a ‘huge fight’ over LiLo’s unwillingness to go public with their lesbian love affair.

Less than a hour later, police stopped Lindsay after receiving a call of a vehicle in hot pursuit of another vehicle; Blohan, in a White Denali, was the ‘Chaser.’ No word on whether Samantha was in the Cadillac Escalade being run down.
