Gossip Girl: A Nasty Piece of Dot Dot Dot

Stylin’ costars Leighton Meester and Taylor Momsen walk the streets on the New York City set of their hit CW show, Gossip Girl.

The show’s latest racy ads have been defaced in subway stations in Manhattan by the “infamous subway ad artist.” Check it out at Gothamist.com. S/he changed the quote from “A Nasty Piece of Work” to “A Nasty Piece of S—”. Sweet, huh?

Leighton told Access Hollywood that she loves the ads (the originals, not the defaced ones): “I think that it’s smart and it’s fine and it’s cool.”

“They’re very smart,” added costar Chace Crawford. “Everybody keeps saying they’re so racy, of course they’re racy, but you say they’re smart.”
