Although they were spotted lunching happily together just last week, it seems all isn't well in the ongoing saga of Lindsay Lohan and Samantha Ronson.
On Saturday night, Linds headed to Playhouse to watch Sam work the turntables.
But according to a source, the two didn't interact at all.
On Sunday night, Sam went to sushi with Drea de Matteo at Nobu in Malibu.
Despite telling photographers that Drea was one of her "best friends," this dinner date apparently didn't go over well with Lindsay. She made a little trip to Sam's house around 6 a.m. to turn up the drama...
X17 has video of L.L. knocking on Sam's door. Once she's finally let in, you can hear the two of them yelling at each other.
But Linds ended up spending the night, so maybe they kissed and made up?
