Lindsay Lohan and Sean Penn are apparently good friends. I find this nothing short of beyond confusing. First off, if I were Sean’s wife Robin Wright, I’d see someone as skanky as Lohan as a serious threat to my marriage. They must have a strong union if Robin’s alright with Lohan and Penn hanging out all the time. According to Page Six, they’ve been spotted hanging out all over Manhattan and now in L.A. Which also begs the question: what’s going on with Lohan and Samantha Ronson? There were all sorts of reports that they’d recently split, but Lindsay is still denying it.

LINDSAY Lohan left her constant companion Samantha Ronson at home the other night to hang with Sean Penn. He and Lohan went to Nobu in West Hollywood, reports Celebuzz.com. Later, Page Six sources said the pair – who were spotted together all over Manhattan last month – went to newly reopened club Guy’s. Ronson and Lohan have been fighting for weeks, and as one tipster told us, “Sam broke up with Lindsay but she is completely in denial about it.”

It seems likely that Lohan and Ronson have broken up. They’re nearly constant companions, yet they haven’t been spotted together since the first of the year, when they had one of their epic fights on an airplane. And hanging out all the time with Sean Penn doesn’t really speak to a healthy relationship. I find that to be such a random and confusing pairing.

It really didn’t seem like Samantha was going to be able to handle Lindsay in the long run. Sam did tone her down and appeared to help her with some of her issues, but a Lohan is a Lohan, and there’s only so much you can do. At this point I’d be seriously surprised if we saw Lohan out with Samantha again, though I doubt she’ll admit to a breakup for a while. At least she has Sean Penn’s shoulder to cry on.
