So it's been about a minute since Justin Long and Drew Barrymore split up.   Is he moving on the the next former child actress already?   The Mac Guy was recently spotted cozying up to Kirsten Dunst!!

[T]he former Mac spokesman, described by friends as "heartbroken" after the split, was hanging out with Kirsten on Wednesday morning... "Justin was holding Kirsten's hand while walking around downtown NYC in the SoHo area," an eyewitness tells OK!. "They stayed out all night and Kirsten was all over him and kept leaning in to kiss him."

Uh, rebound much?  And speaking of Kiki, wasn't she dating Ryan Gosling?  Good lord, I'm confused!!
