And They Said It Would Never Last..

After just a few months, some marriage rumors, a few cooter slips, some extra large condoms, a lost and found Hermes bag full of $1 million in jewelry, an almost-firing, couples tatoos, a public spat with mom and a broken arm, Harry Morton has kicked Lindsay Lohans trashed ass to the curb.

"Harry broke up with Lindsay yesterday at Chateau Marmont after they had dinner on the courtyard patio," a source tells PEOPLE. "Nothing happened at dinner, but shortly afterward, he broke up with her." Why the split? "She was too much drama," says the source. "Lindsay did cut down on the partying, but with her it's all relative. Harry is sober. It wasn't the partying that broke them up. She's young and a little bit immature. Harry's more low-key and not into the same stuff she's into." Yeah, like he's into stability and she's not. However, a source close to Lohan says, "No one 'dumped' anyone. You don't dump people when you're 20 and 25. You have a mature relationship, and you take a break and you see what happens. Everyone does that." In other words, her ass was DUMPED!

Lohan's rep could not immediately be reached for comment. A rep for Morton said, "I do not comment on his personal life." Indeed, Lohan, 20, was spotted at Hollywood's Chateau Marmont on Thursday, running onto the patio where four of her friends were sitting – and weeping, a wad of tissues on one hand, her cell phone in the other. "She ran in, sat with her group, put down her cell phone and cried to her pals," an observer tells PEOPLE. "The group looked very concerned and listened intently to what she was saying." After the Chateau, Lohan went to Hyde Lounge, where she arrived around 12:30 a.m. and stayed until the hot spot closed at 2 a.m. She mingled with friends and didn't appear to be distraught: "She was having a blast," says one patron, "even with a broken hand."
