Things have gone sour between Lindsay Lohan and Samantha Ronson!
Why? And who's to blame? Lilo or Sam?

Lilo and Sam split up last week and it seems Samantha's family are ecstatic about it!
Some reports state that it's Lilo's fault, while others claim that Sam is behind the break-up.
We all already know about Lilo's troubled past and her hard partying ways and other erratic behaviors, so it would be more logical to assume that Sam wanted out and Lilo is the reason of the split! No?

The other day, Lindsay tried to get into the "I Heart Ronson" party at Bar Marmont, where Sam was deejaying, but was banned!
Obviously, Sam doesn't want Lilo there. Ouch!

Sam even changed the locks on her house to make sure Lindsay doesn't have access to it. Double Ouch!

It seems it's all down to this, Sam has had enough of Lindsay's attitude, fiery personality and uber-drama!
Lilo is over protective, jealous, needs a lot of attention and usually has an erratic behavior.
Sam doesn't hate Lilo, she's just fed up and can't deal with it any more. She wants all this to end.

I wouldn't blame her!
