OK Magazine seems to think they know the real deal behind Lindsay Lohan and Samantha Ronson’s problems. According to the mag, Lindsay was spotted stopping by “Gossip Girl” star Chace Crawford’s apartment at six in the morning. All of this while Samantha is supposedly recuperating from an ear infection in Los Angeles.

While the cat’s away, the mice play — that’s how the saying goes, at least. And, though she’s denying any trouble in her romance with girlfriend Sam Ronson, Lindsay Lohan has only been feeding the rumor mill with her behavior.

See, while Sam has been recuperating from an alleged ear infection in Los Angeles, Lindsay’s been party-hopping, and according to TMZ, that includes a 6am pop-in visit to the Big Apple apartment of Gossip Girl hunk Chace Crawford.

While the I Know Who Killed Me star denied any illicit goings-on with Sir Chace of Sexyshire, there is a bit of little-known history between the two young stars.

Back in Oct. 2008, Linds made no secret of her crush on Chace. The twosome met at the Diesel XXX Rock Party in NYC and swapped numbers and an insider tells OK! that Lindsay texted Chace nonstop.

“She has a habit of over texting people, especially when she’s attracted to them which is what happened with Chace. She’d have insomnia and he’d wake up to 5 or 6 text messages asking what he was up to. She has a habit of getting bored in the middle of the night and likes to flirt and get attention in order to keep her busy. Chace never acted on some of the things she suggested like meeting up, it was a little stalker like and creepy to be honest. He was just trying to be friendly!”

I don’t know much about Chace Crawford, but somehow he seems too classy to hook up with Lohan. I mean that’s practically career suicide – no one respects you once you’re linked to Lindsay. And it’s fair to point out that other people obviously live in Crawford’s building – in fact, Crawford is roommates with his “Gossip Girl” costar Ed Westwick. Considering the way Lohan gets around, she could have been there for anyone.

It seems like the relationship between Lohan and Ronson is on its last legs. I get the feeling Lindsay’s just keeping it alive for the publicity – it doesn’t look like there’s anything left between the two. Once Lohan goes back to hooking up with every guy in town, people aren’t going to care anymore. Really, all she’s got left, novelty-wise, is dating someone really, really old or really, really wealthy. She’s hooked up with everyone else.
