Gossip Girl continues filming new eps for their second season on the streets of NYC this week and he was snapped shooting a kissing scene with one of his GG co-stars … and you’ll never believe who it is:

Now, because this scene involves an ep that hasn’t aired yet, I’ll keep the revelation behind the cut for those of you who do not wish to be spoiled by these pics. After the jump, those of you who are dying to know who Chace (or, his character Nate rather) is making out with can see a few more pics …

OMG! It’s Taylor Momsen … who plays little Jenny Humphrey:

What the hell …? I am actually pretty surprised by this pairing. I can’t wait to find out what circumstances will lead to this hook-up. Love that Taylor has to reapply her cherry Chapstick in between takes. OMG … what will Dan Humphrey say about this?
