Lindsay Lohan LindsLocksmith200.jpgLOS ANGELES, California (X17online) - Lindsay Lohan and her girlfriend were involved in a loud fight at their home in the Hollywood Hills, Monday night.

X17online photographers outside the house heard crying and screaming. Around 10:30pm a locksmith showed up at the house. Later Samantha told photographers outside that she locked herself in the bathroom.

"It sounded like Lindsay was going crazy in there - like a toddler throwing a temper tantrum. We've heard them fight before, but they've never had to call someone to the house like this!" the photographer said.

Lindsay wouldn't come out of the house, eyewitnesses could hear her crying and screaming, "I never cheated on you!"

Sam seemed calm and collected when she emerged from her house half an hour later, but sources say that she may have locked herself in the bathroom to get away from Lindsay, and that it was LINDSAY who called the locksmith to open the door.
