Kirsten Dunst spotted kissing Drew Barrymore?s recent ex, Justin Long

I'm constantly amazed by the seemingly random hookups between celebrities, single or otherwise attached to other people. The young celebrities seem particularly prone to in-dating, which makes sense because they're the ones who are less likely to settle down.

Kirsten Dunst, 26, was spotted out looking bleary eyed and walking hand in hand early in the morning with Justin Long, 30, whose separation with girlfriend Drew Barrymore was just announced. It's assumed that since Kirsten and Justin - that has a cute ring to it - were together in the morning that they spent the night together. And they were holding hands and kissing so it's not likely that one of them just crashed on the couch because they were two drunk to drive home.

"Justin was holding Kirsten's hand while walking around downtown NYC in the SoHo area," an eyewitness tells OK!. "They looked like they had stayed out all night and Justin had bloodshot eyes, but Kirsten was all over him and kept leaning in to kiss him."

Perhaps they were heading to the 30-year-old's new digs -- Justin recently purchased a $2.4 million bachelor pad in the Big Apple.

The scene was in stark contrast to Justin's disposition less than a week ago when he was still reeling from his split with Drew. While out at Westside Tavern on July 12, the actor looked "heartbroken," a source tells OK!.

Dunst was most recently casually dating a 25 year-old DJ/actor named Matt Creed. In Touch reported last week that they were seen eating out one day and out at a bar together a few days later.

Kirsten tends to hold her relationships close to her chest so it's not likely that we'll be hearing gushing reports about how great Long is or seeing the two of them hit the paparazzi targets like he did with Barrymore. It seemed like Barrymore was the one who wanted to announce her relationship with Long to the world and that he just happily went along with it. He seems like a great guy and he doesn't strike me as the grungy rocker type that Dunst seems to usually date. Maybe he's just the kind of guy that she needs now. I think I see the faintest hint of a smile on her face in these pictures.
