Blake Lively and Leighton Meester were spotted shooting scenes in front of the Met, while Meester and Ed Westwick filmed a different kind of scene. Everyone's favorite snooty, yet oh so vulnerable and misunderstood couple, Blair Waldorf and Chuck Bass got all lovey-dovey while shooting a scene. Who cares, you ask? Well, thanks to these photos, we give you the Chuck Bass Guide To Kissing. Check it out... Step 1: Make sure the girl knows you're going to kiss her. We don't need any more kinda sorta date-rape incidents!
Step 2: Start lightly, then...
Step 3: ...Go in for the kill.
Step 4: Make sure she can't resist the Bass charm (minus any illegal substances).
Step 5: Make sure she knows who the prettier person in the relationship is.
Step 6: Walk away feeling like a motherf------g pimp. But beware of packs of wild teenage girls.
Step 7: Leave her wanting more.
Bonus step 1: Yeah, this is never a good look. Extra magic needs to be worked.
Bonus step 2: If you see her gossiping, make sure you're far away. Far, far away.
Bonus step 3: Sometimes you need to admit the other person is way hotter than you. It's a good ego boost.
