Lindsay Lohan and Samantha Ronson have reportedly split up again. Although, it was really questionable at best if they were even back together in the first place, depending who you ask. (Hint: If you ask Lindsay they totally were.)

"Sam let Lindsay back into her life as a friend, but now even a friendship seems impossible," says the source. "No matter how many times she promises to change, Lindsay loses control and starts acting like a maniac."

"She is telling everyone that Sam dumped her again, but it makes no sense since they never got back together," according to the source. (Source)

Acting like a maniac? Whatever could that mean? I'm sure it probably almost definitely doesn't have anything to do with Lindsay stalking Sam around London and then pretending that they were enagaged. Because that's totally normal behavior when you're trying to get your ex back. I bet she did something really crazy, like threw a drinking glass across the room during an argument. I mean, really. There's just no bouncing back from that.
