Lindsay Lohan LLohanSamN091908_04_X17.jpg The Daily Mail is reporting that Lindsay Lohan and girlfriend Samantha Ronson have hit a rough patch in their lovey dovey relationship, and Sam is becoming frustrated with Lindsay and her hard partying ways.

Samantha reportedly feels "smothered" by Lindsay and the constant media attention, and she's beginning to realize that things may not change. A source for the paper claims that even though Lindsay acts "obsessive" at times, she may still be interested in men, and Samantha is beginning to question the long term potential of their relationship.

The source reveals:

    "Sam needs her space away from Lindsay and really needs to take a long look at what the future of this relationship can be. Sam's friends have been saying for a while that Lindsay still likes men as well as women. And for Lindsay's part, she's still caught up in her partying ways. Samantha doesn't need that in her life, not now, not ever. If these two are going to be together for the long term, Lindsay is the one who's going to have to change, calm down, and get real. Sam's made that very clear to her."


On Lindsay interfering with Sam's work:

    "Clearly, they were spending a little too much time together, and Samantha was the one who said Lindsay was getting in the way, and even acting obsessive at times. Samantha DJ'ed three big parties around the Emmy weekend in Los Angeles, and Lindsay was practically on top of her for every minute of those gigs. Lindsay was behaving in a very smothering way. For a man or a woman, it can be hard when your girlfriend insists on going to work with you every day. The problem here is that Samantha is intent on being taken seriously as a DJ, and the Lindsay sideshow was starting to overwhelm that."


On the couple's recent vacation to Cabo:

    "The vacation was all about fixing their relationship, because things had gotten dicey in late August and early September as Lindsay and Sam were just getting so much attention - so much that they needed to get out of the country for a while. But things didn't go well in Mexico. Despite the photos of them playing on the beach, Sam said things were very tense between them when they got back. She's known for being shy, but what she's less known for is being a very serious and thoughtful person, and there have always been these second thoughts about how she comes across being in this high profile 'celebrity romance'. It's never been something Sam's been willing to embrace the way Lindsay does. Going to Mexico kind of confirmed a lot of that stuff for Sam."


Think these two could really be on the outs? They've been together for so long, and they always seem so happy together! We're not sure what to believe!
