Lindsay Lohan

Hmm, trouble in paradise?

On Tuesday night, photogs waiting outside of Samantha Ronson's Hollywood Hills home tell X17online exclusively that they heard a screaming catfight between the DJ and her lady love, and that this sort of thing happens all the time! Shocking, right?

An X17 photog tells us, "The noise was pretty frightening. It was the two of them screeching at one another, and you could hear stuff being banged around too - it sounded like a lovers' quarrel, but a pretty bad one!"

Last night, a very irritated looking Lindsay was snapped coming out of Sam's pad, and after she hopped into her brand new Benz, she stopped at the end of the road and called the police. Apparently the starlet wanted to block photogs from following her, and once the police arrived, she went on her way, unfollowed.

Maybe someone had another screaming match with their lesbian lover last night? We're not sure, but Lilo was definitely in a rotten mood!
