Exclusive: So Kirsten Dunst, Josh Hartnett And An Olsen Twin Walk Into A Bar...

Silly Kirsten Dunst. Temporarily living outside of her natural celeb-friendly West coast habitat where any late-night messiness is handily kept on the DL by celebrity-catering club warlords, the recently rehabbed star is currently staying in New York while filming All Good Things. And the many sightings sent in by helpful Manhattanites haven’t exactly painted Dunst as the soberific poster child perfected of late by Miss Lindsay Lohan. The NY Post chimes in today reporting that Dunst continued her boy-crazy habits of yore by making out with the DJ at the celeb-infested Beatrice Inn two nights ago. But a Defamer tipster had the pleasure of spotting Kirsten last night at the same bar, and rather than cozying up to the same DJ, the actress spent the entire night flirting, following, and eventually frisking another Beatrice regular: that talented thespian, Josh Hartnett. Details on what our tipster witnessed, and which Olsen twin watched the romance blossom from afar, after the jump.

We'll let our informant take the floor and set the pre-Hartnett scene for us:

"Kirsten came in on the early side with a matching blonde wingwoman, and she definitely didn't look like the dirty-haired slob most sightings have depicted her as. She was bubbly, giggly, bouncing from friend to friend near the bar and enjoying the music upstairs. At one point she asked me for a cigarette and a light, so I handed her one, but before I could fetch a lighter, some heroic hipster-y looking guy swept up and took over celebrity cigarette lighting responsibilities. She was smiley all night, wearing a girly grunge flannel shirt and skinny jeans. The Olsen twin came in with a huge posse around the same time, but the two stars didn't say a word to each other all night. The MK/Ashley hybrid planted herself by the DJ's booth and chain-smoked all night while hush-hush gossiping with a tight group of friends."

But it seems that as soon as master thespian Josh showed up around 1am, Dunst abandoned her cigarette bumming and devoted all her attention to the newly shaven star:

"As soon as Josh came in with a couple of wingmen of his own, Kirsten went straight towards him and spent a good half hour laughing and chatting him up by the bar — their faces were so close, they might as well have been eskimo-kissing. And even though Kirsten followed Josh whenever he changed rooms, up the stairs when he went up to survey the dance floor still lorded over by the seated Olsen, and down the stairs when he needed a refill, he was definitely reciprocating. The one non-nauseating sight? Didn't see Dunst take one sip of anything. MK/Olsen/Whichever, on the other hand..."

The icing on the cake? Another source tells us, "My friend saw Josh and Kirsten leave together." And somehow we doubt all that flirting didn't end with a handshake on the curb.
