I never really know what to think about Josh Brolin. He seems like he’s one of those work-hard-and-party-even-harder kind of dudes. I loved him in several films, and I do think he’s a crazy-talented actor. But in interviews, he sometimes seems… I don’t even know. I can’t put my finger on it. He doesn’t come across as arrogant, just cavalier, maybe? He also seems like he’s probably a high-functioning alcoholic. He just has that vibe to me, but I could totally be wrong. Anyway, this week’s Enquirer is trying to start a rumor about Josh cheating on his wife Diane Lane – with his friend and frequent costar Marley Shelton. Now, this isn’t the first rumor about Josh’s wandering eye. Allegedly, at this time last year, he hooked up with some chick in New Orleans, and Diane later “forgave” him. This time the “affair” seems based on a set of photos the Enquirer has of Josh and Marley having coffee and then hugging and kissing each other as they said goodbye. That’s it. Seriously.

Oscar-nominated Milk star Josh Brolin has been photographed in what looks like a steamy lip lock with a sexy actress – who isn’t his wife Diane Lane!

Brolin, 42, kissed and hugged 36-year-old married beauty Marley Shelton after a coffee date in Santa Monica on April 28.

“Josh and Marley sat at an outside table for at least 30 minutes, sipping coffee and talking animatedly together. Josh was not wearing his wedding ring,” said the witness. “As they walked away, Marley reached out to put her arm around Josh’s shoulder. A moment later, they kissed full on the lips and she pulled him close with her free hand.”

“When they parted, she walked to her car. It had a baby seat in the back and a stroller in the trunk.”

Marley has costarred with Brolin in three films – Women In Trouble, W, and Grindhouse. She has an 8-month-old daughter with her husband of nine years, producer Beau Flynn.

Just two days after cozying up to Brolin, Marley was arrested on suspicion of DUI. She was released on $5,000 bail after being pulled over in Hollywood around 10:30 p.m. and reportedly failing a field sobriety test. But Brolin’s rep Liz Mahoney insists nothing improper happened between Marley and her client.

“Josh and Marley are dear, dear friends. They’ve done three movies together and this was just an embrace between old friends,” she told The Enquirer.

Brolin’s marriage to Diane, 45, has been stormy. Just four months after they wed in 2004, he was arrested on a misdemeanor charge of domestic battery after Diane called the police. The charge was later dropped.

He and Diane were last photographed together on April 10 while walking their dog in Venice. Recently, she was in Louisville for the Kentucky Derby, while Brolin was in NYC for the Tribeca Film Festival.

Should Josh get a pass, considering the story seems totally vague and random, based solely on two friends going out for coffee? Probably. I looked at the photos, and while it seemed slightly weird that Marley and Josh kissed on the lips, it wasn’t a sexy kiss at all. It just looked like two friends saying goodbye in the street, and giving each a quick peck. But has Josh earned this pass? Eh. I wouldn’t be surprised if he was screwing around on Diane in general (and for that, he’s a pig), but I just don’t think in this one insistence he was carrying on an elicit coffee-meeting affair.
