Sienna Miller and Josh Hartnett Are So Totally Doing It

I don't know why publicists bother to deny the obvious truth. Everyone knows that when celebrities come within five feet of each other, they are automatically dating, nevermind when they have an intimate conversation, and touch each other on the leg. That's practically like being married. And that's exactly what Sienna Miller and Josh Hartnett were doing at the Chateau Marmont on Tuesday night, reports People.

Miller, 25, and Hartnett, 28, sat side-by-side on a couch in the hotel restaurant's living room area, laughing and chatting for about an hour before they were joined by a female friend of Miller's.

But they kept things intimate - at one point, Miller stood in front of a seated Hartnett, who held on to her thigh with his hand. The pair eventually headed out, cocktails in hand, to the hotel's poolside bungalow area.

So are the single actors (she split with Jude Law in November; he most recently dated his Black Dahlia costar Scarlett Johansson) an item? "They're friends, just friends," Miller's rep tells PEOPLE. "They were just hanging out."

Seconds a rep for Hartnett: "There is nothing to comment on."

"Just hanging out." Right. We all know that the more a publicist denies it, the more it's true. But whatever. I'm sure they're not dating. Just like I'm sure Lindsay Lohan really was just drinking water...
